物理缔合高分子溶液的相分离及凝胶化

Phase Separation and Gelation of Physically Associating Polymer Solution

利用格子自洽场理论模型研究物理缔合高分子溶液的相分离及凝胶化行为.给出了相分离和凝胶化点随高分子浓度和相互作用参数的变化规律及高分子链聚合度对相分离及凝胶化的影响.结果表明,凝胶网络的形成影响了系统的相分离.

Self-consistent field model was used to study the phase separation and gelation of physically associating polymer solution. The variations of the locations of the phase separation point and the gelation point with the polymer concentration and interaction parameter were investigated. The effect of polymerization on the transition was also studied. The formation of the gel network has a significant effect on the phase separation of the system.
