摘要：

Weak segregation theory is applied to studying the phase behavior of a melt of a binary multigraft copolymer with polydisperse side chains regularly spaced along the backbone. The resulting phase diagrams of the melt show an increase of the temperature of transition to an ordered state with increasing coefficient of polydispersity of side chains. The effects of the average length of the side chains and the distance between the points of their grafting on the phase diagram of the melt are examined.
