摘要： 互穿网络聚合物(IPN)的平衡溶胀度及溶胀动力学特性与聚合物的微观形态结构有关.甲基丙烯酸甲酯(MMA)可在蓖麻油聚氨酯(COPU)中聚合形成典型的具有两相结构 的AB交联聚合物.COPU/PMMA重量比70/30为该体系的相逆转点,此时为双连续相,在此比例上、下分别为COPU连续相,PMMA连续相.

关键词: 蓖麻油聚氨酯, 聚甲基丙烯酸甲酯, 交联共聚物, 溶胀, 相逆转

Abstract: The swelling of castor oil polyurethane/polymethyl methacrylate crosslinkedcopolymers in a number of solvents has been studied.It is found that the swelling behavior isin relation with the presence of the continuous phase in the crosslinked copolymers and thebinary diffusion coefficients are able to reflect the phase inversion of the copolymers.

Key words: castor oil polyurethane, polymethyl metharylate, crosslinked copolymer, swelling, phase inversion
