Phase behavior of AB-multiblock copolymer melts which consists of chains with laser distribution of A and B blocks have been investigated in the framework of the mean-field theory, where the polydispersity of copolymer is a function of two parameters K and M. The influence of the Laser...

The phase diagram of AB-multiblock copolymer melts containing A and B blocks obeying the Laser distribution, has been investigated for various values of the parameters K and M. As M→∞ it reduces to the ordinary Schultz–Zimm distribution. With decreasing M, the transition lines of the...
