研究了半连续和间歇式丙烯酸酯三元乳液共聚产物的形态和分子结构。结果表明,半连续式胶乳粒子呈“多核核壳结构”,其粒径和粒径分布随单体滴加速度减慢而变小。间歇式胶乳粒径较大,粒径分布亦更宽,呈硬相在外的“单核核壳结构”;共聚物分子链中VAc结构单元的序列较长。两种方法所获无规共聚物均存在微相分离结构,分离程度随单体滴加速度的加快而变大。 The morphology and molecular structure of the copolymerization products of semi-continuous and batch-wise acrylic terpolymers were studied. The results showed that the semi-continuous latex particles were “multi-core core-shell structure”, the particle size and particle size distribution decreases with the monomer dropping rate becomes smaller. Intermittent latex particles larger particle size distribution is also wider, the hard phase outside the “mononuclear core shell structure”; copolymer chain VAc structural elements in the longer sequence. The random copolymers obtained by the two methods all have micro-phase separation structure, and the degree of separation increases with the increase of the monomer dropping rate.
