  Abstract:
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 SchultzZimm distribution. With decreasing M, the transition lines of the lamellar, hexagonally close-packed cylinders and body-centered-cubic phases shift to greater N× X, so that for high K these shifts are very large while for low K they are very small.
