通过ＤＭＳ、电镜、平衡溶胀比、密度等测定研究了将丙烯腈、醋酸乙烯酯等乙烯基单体作为共聚组分引入全（甲基）丙烯酸酯Ｌ’ＩＰＮ（胶乳型互穿聚合物网络）中对共混体系相容性的影响，发现：种子乳液聚合所形成的Ｌ＇ＩＰＮ具有“核－－壳”结构；通过无规共聚引进不同链结构能显著地调节ＩＰＮ（互穿聚合物网络）的相容性；在一定范围内提高Ｌ’ＩＰＮ中的网络密度对提高共混体系的相容性是有效的；密度效应在ＩＰＮ共混系统中存在，但其正负偏差的同时出现体现出ＩＰＮ结构的复杂性。
The effects of acrylonitrile, vinyl acetate and other vinyl monomers on the copolymerization of all (meth) acrylate L’IPN (latex type interpenetrating polymer network) were investigated by means of DMS, SEM, equilibrium swelling ratio and density. The results showed that the “IPN” formed by seed emulsion polymerization has a “core-shell” structure; the introduction of different chain structures by random copolymerization can significantly adjust the IPN (Interpenetrating Polymer Network ); It is effective to improve the network density in L’IPN to improve the compatibility of blends within a certain range. The density effect exists in the IPN blends, but the positive and negative deviations appear at the same time The complexity of the IPN structure.
