Plastic is a polymer, meaning it is a chain of small similar units all connected in a single molecule.  Usually it is made by taking a solution that consists of the building block units (called monomers) and including whatever chemicals will make the monomers bonds together.  The mixture is put into a mold and heated, and the resultant polymer has huge, inter-tangled chain molecules that become rigid and hard.  The mold is removed, and voila.

Dichloromethane will dissolve most plastics except for PTFE, PFA, or FEP. if you could find a transparent plastic coated with any of these, it might work.

Ethylene-vinyl acetate (also known as EVA or sometimes simply as "acetate") is the copolymer of ethylene and vinyl acetate. It is a polymer that approaches elastomeric materials in softness and flexibility, yet can be processed like other thermoplastics. The material has good clarity and gloss, barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive and heat sealing properties and resistance to UV radiation. EVA has little or no odor and is competitive with rubber and vinyl products in many electrical applications. EVA foam is used as padding in equipment for various sports such as hockey, boxing, and mixed martial arts.\n\nA polyurethane is any polymer consisting of a chain of organic units joined by urethane links. It is widely used in flexible and rigid foams, durable elastomers and high performance adhesives and sealants, fibers, seals, gaskets, condoms, carpet underlayment, and hard plastic parts.

There are all kinds of different materials lumped under the generic heading of "plastics".  The variations run into hundreds, perhaps even thousands of compounds!\n\nFor example, there's nylon.  The most familiar form, nylon 66, is a copolymer of adipic acid or adipoyl chloride and hexamethylene diamine.  But I can substitue various hydrocarbon chains in those two components to make nylon 55, nylon 65, nylon 48, nylon 83, etc.\n\nThen there are the families of polyaramid polymers, and polyester polymers, and polycarbonates, and . . . .\n\nNobody will ever be able to give you an exhaustive list here.  Try looking up some books on polymer chemistry at your library.

Well that is a loaded question. But I will try and simplify it as much as possible. A polymer is a molecule or compound whose intrinsic shape allows it to attach to others like itself.  ( it gets deeper than this but I am trying to keep it simple) polymers are common both in nature (Gaba Bean) and syntetically.  As amatter of fact you probabbly have several polymers in your place of residence at this moment.\n\nNow for some meat, Most Plastics are by definition polymers. for example PVC Pipe or poly Vinyl chloride is nothing more than a continuois linking of thsame molecule.  On another note Gelatin is a polymer that puts the jiggle in jello. when this polymer is combined with water and subjected to temperature a polymerization reaction occurs which is nothng more than the gelatin bonding to itself forming a latice network that "coagulates" the water into the desire of all children.  Polymerization goes much deeper than this but I hope you get the point.  If you dont then try this illistration. humans are basically identicle in shape. gather as many of your friends together as possible an hold hands. you have now demontrated the basic idea of polymerization.  I appreciate your interest in knowledge. How can anyone expect to gain knowledge if they never ask.

I'd sure be cautious with any Methylene Chloride!  It is highly volatile and it is a carcinogen.  Nasty stuff!  I would first try a strong detergent and steam.  Steam will loosen a lot of compounds that you wouldn't expect to respond to heat and water alone.\n\nJohnny

Unplasticised Polyvinyl Chloride\nPolymer Type \nThermoplastic\nAdvantages \nCheap, good acid and alkali resistance.  Flame-retardant.  Stiff and strong.  Can be transparent.  Good vapour barrier properties.  Good UV resistance.\n Disadvantages \nDifficult to melt process, requires modification.  Limited solvent stress cracking resistance.  Becomes brittle at (c 5°C (40°F) ) unless impact modified.  Low continuous service temperature of 50°C (120°F).\n \nPB--Polybutylene\nIt is a certified and acceptable material--but, there are class-action lawsuits b/c it leaks under certain circumstances.\n\nPPR--Polypropylene\nPPR pipe was promoted and recommended by China Construction Material Bureau and the people of PPR industry last year, and quickly PPR pipe take over the market of PAP composite pipe and occupy about 60% of total plastic pipe market in China because of the advantages :\n\n1. PPR pipe's installation is same as steel pipe, local construction designers get used to it.\n\n2. PPR pipe don't need fitting. Many accidents of PAP composite pipe (also PEX pipe) is caused by the broken between copper fitting and pipe before, leave bad impression on China Construction industry. \n\nPPR compound is made by 90-95% PP, 5% Ethylene and other additives, is compounded by the twin-screw extruder, the compounding temperature is close to Sioplas compounding. According to the specification released by China Construction Material Bureau, PPR pipe with 3.5mm diameter can pass the testing under 1000 hours, 95 C and 3.5Mpa. For the same requirement, PEX pipe only need 2.7mm diameter. Now flooring-heating pipe become popular in northeast China and will expand to northwest China soon.

cellophane is a plastic but not all plastics are cellophane.   Nylon is a plastic. Teflon is a plastic. etc...\n\nMaking Cellophane\n\nIn the manufacturing process, an alkaline solution of cellulose fibres (usually wood or cotton) known as viscose is extruded through a narrow slit into an acid bath. The acid regenerates the cellulose, forming a film. Further treatment, such as washing and bleaching, yields cellophane.

Currently, the polymer sodium polyacrylate.  It is nicknamed "super slurper" because it can absorb 400-800 times its body weight in water.  Oh yeah, it is used in a variety of applications, including diapers.  Pretty cool, huh?

Tin(II) chloride (stannous chloride) is a white crystalline solid with the formula SnCl2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating. Tin(II) chloride should not be confused with the other chloride of tin, tin(IV) chloride or stannic chloride (SnCl4).

A polymer is a a bunch ("poly") of chemically bonded chain members ("mers")\n\nA very common example is polyethylene, in which the mer is ethylene:\n\nCH2=CH2   ----> [-CH2-CH2-]n\n\nThis results in a linear chain.\n\nAn appropriate mer for polymerization must have some kind of way to bond to at least two other mers.  A double bond can be opened to form bonds with two other things.  Carboxylic acids can form bonds with alcohols and amines to form ester or amide linkages.\n\nIf you have the ability to form MORE than 2 bonds with other mers, you have the ability to form a crosslinked polymer (sometimes called a network polymer)\n\nFor example, if you have a di-acid molecule, it could form a polymer with a di-alcohol.  If you use glycerol as your alcohol (glycerol has 3 alcohol groups instead of 2) you can form a cross-linked network polymer.\n\nAnother way to form a crosslinked polymer is if useful chemistry remains in the polymer after the polymerization reaction.  For example, butadiene has two double bonds in it, and after the polymerization reaction, it still has one double bond per mer unit in the chain.  If you add sulfur to the polymer and heat it up, the sulfur can react with the existing double bonds to form disulfide bridges that connect two chains together--these are called cross-links.\n\nThe vulcanization of rubber is an example of chemically crosslinking a polymer (butadiene is chemically similar to rubber).  Tires are made out of this rubber.\n\nCross links provide a mechanical limitation on the stretchability of polymers.  Normally, a polymer can be stretched slowly because over time the chains can slide past each other (like pulling apart noodles from a pot of cooked spaghetti).  Cross links prevent the noodles from sliding past each other because all the noodles are mechanically bonded to each other at a few places.
