| 摘 要： | <正> 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。

| Abstract: | Phase transition processes of benzoylated poly (phenylene oxide) with styrene-butadiene-styrene copolymer blends were studied by using light scattering. The results show that the phase separation at early stage follows the Cahn's theory. In later stage, the phase separation processes were found to give the scaling law on the wave number of the dominant Fourier component of the fluctuation qm(t) and on the maximum scattered intensity Im as given by qm - t-a and Im -tβ.
