为了模拟多组分高抗冲聚丙烯(HIPP)的相分离及其形态, 我们运用自洽场理论(self-consistent field theory, SCFT)研究了均聚物A/均聚物B/两嵌段共聚物A-b-B/交替共聚物(A-b-B)4四元共混体系的相分离及形态演化, 着重讨论了各种组分的链长和含量对体系形成各种多层核壳结构的影响.

关键词: 自洽场理论, AB两嵌段共聚物, 交替共聚物, 四元共混物

Self-consistent field theory was employed to calculate the morphology of A/B/A-b-B/(A-b-B)4 quaternary blending system, which can be used for simulating the phase structure of high impact polypropylene (HIPP). We focused on the influence of chain length as well as the volume fraction of each component on the phase behavior of blends and confirmed that the system can phase-separate into various core-shell structures.

Key words: self-consistent field theory (SCFT), AB diblock copolymer, alternating copolymer, tetra-component blends
