| 摘 要： | 讨论了在聚氨酯水分散体中进行丙烯酸酯共聚物乳液聚合的一些特征。研究表明，聚氨酯水分散体起着种子乳液的作用，发生了核－壳型事过程；复合乳液中聚氨酯链形成其壳，聚丙烯酸树脂分子链形成其核，二树脂的分子链相贯穿与缠结，形成了互穿网络结构。

| Abstract: | The features of emulision polymerization of acrylic monomers in a polyurethane dispersion were investigated. The polyurethane dispersion was used as a seed emulision in this core-shell latex polymerization process, yeilding an IPN structure of core-latex polymer in which the acrylic particle was entirely surrounded by the anionic urethane outer shell. |
