摘要

聚合物合成工艺往往会使聚合物原料的分子链链长呈现出长短不一的状态，这就使得该聚合物的分子量分布呈现出多分散性。而这种多分散性的分子量分布会对不同性质的聚合物共混体系的相行为产生不同的影响。本文阐述了研究分子量分布对多相多组分聚合物体系的相行为影响的重要性，并分别从高分子溶液体系、嵌段共聚物、聚合物-聚合物共混体系、胶体-聚合物共混体系这四个方面综述了分子量分布对多相多组分聚合物体系的相行为产生的不同影响，同时提出了该领域今后的研究方向。

Abstract

During the polymer material synthesizing process

polymer synthetic technologies can make polymer materials be composed of various lengths of molecular chains

which leads to the molecular weight distribution is polydisperse.However

this polydispersity will result in different influence on the phase behavior of different polymer blending systems.In this paper

the importance of researches on the effect of polydispersity on the phase behavior of polymer systems is described.The effect of polydispersity on the phase behavior of polymer solution

block copolymer

polymer-polymer blends

colloid-polymer blends are reviewed and the directions of future research in this field are proposed.
