对高分子-高分子共混体系相分离动力学过程的研究,人们一般局限于均聚物-均聚物,均聚物-无规共聚物共混体系,对于均聚物-嵌段共聚物共混体系的分相过程很少涉及。原因其一是很难找到具有临界相行为的嵌段共聚物-均聚物共混体系,其二是嵌段共聚物存在微相分离,使得宏观相分离动力学过程研究变得复杂。Paul的工作似乎为这方面的研究工作开辟了道路。
The polymer phase - polymer blends phase separation kinetics research, people are generally confined to the homopolymer - homopolymer, homopolymer - random copolymer blends, homopolymer - block copolymer Blending system phase separation rarely involved. One of the reasons is that it is difficult to find the block copolymer-homopolymer blends with critical phase behavior. The second is the existence of microphase separation of the block copolymer, which complicates the study of macroscopic phase separation kinetics. Paul’s work seems to open the way for research in this area.
