3 for $b=2$, and 0.0211 for $b=3$ fractal, equal to $D^*$ for the corresponding cases $v<v_c(u_\theta)$ of the ASAWs model.

-   When $w=w_c(u_\theta,t)$, the RG parameters tend to the fixed point $$\label{fpt2}
      (A_\theta,B_\theta,C^*,A_1^*,A_2^*,A_3^*,A_4^*,B_1^*,
     B_2^*)\>,$$ which corresponds to the phase in which chains are not segregated anymore, but they are not yet completely entangled. In contrast to the $w=w_c(u<u_\theta,t)$ case, for which symmetrical fixed point is obtained, values of $A_i$ $(i=1,2,3,4)$, as well as $B_1$ and $B_2$, are not mutually equal ($A_i\neq A_\theta C^*$, $B_i\neq
    B_\theta C^*$). The scaling relation $\langle M^{(r)}\rangle\sim
    \langle {N_3}^{(r)}\rangle^{\varphi}$ is satisfied, with $\varphi$ given by (\[fie2\]).

-   For $w>w_c(u_\theta,t)$ the RG parameters flow towards the entangled fixed point (\[fp5\]).

Strong self-attraction of the 3D chain
--------------------------------------

When self-attraction of the 3D polymer is strong ($u>u_\theta$), depending on the values of inter-chain interaction parameters, the following phases are possible:

-   For $w<w_c(u,t)$ the chains are segregated. Due to the large compactness of the 3D chain, with $(A^*,B^*)=(0,B_G)$, none of the configurations $A_1,A_2,A_3,A_4,B_1,B_2$ can be accomplished, and the corresponding fixed point is $$\label{fpg1}
    (0,B_G,C^*,0,0,0,0,0,0)\, .$$ The chains are completely separated.

-   When attraction between the chains is critical, $w=w_c(u,t)$, the chains are partially entangled, and the fixed point $$\label{fpg2}
    (0,B_G,C^*,0,0,0,0,B_G C^*,B_G C^*)\>,$$ is attained. In this case the interaction between chains is sufficiently strong to connect them, but not strong enough to destroy the compactness of the 3D globule, so that all $A_i^*=0$. Again, the scaling relation $\langle M^{(r)}\rangle\sim \langle
    {N_3}^{(r)}\rangle^{\varphi}$ is satisfied for both $b=2$ and 3, with $\varphi$ given by (\[fie2\]). However, while in the case $b=2$ the coordinates of corresponding fixed
