| 摘 要： | 采用半连续种子乳液聚合,以丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)、乙酸乙烯酯(VAc)为主单体,丙烯酸(AA)为功能单体,叔碳酸乙烯酯(VeoVa10)为改性单体,合成了核壳型丙烯酸酯乳液。探讨了聚合温度、乳化剂、引发剂及功能单体与乳液性能的关系。通过单因素实验探讨了乳化剂用量、配比,改性单体用量等与乳液性能的关系。FT-IR和DSC测试结果表明,各单体之间发生了自由基共聚反应,乳液粒子为核壳结构。

| Abstract: | The core-shell poly acrylate emulsion was prepared from n-butyl acrylate BA ,methyl methacrylate MMA vinyl acetate Vac as the base monomers,acrylic acid AA as the functional monomer,and vinyl versatate(VeoVa10)as the modifying monomer by semi-continual seed emulsion polymerization.The effects of reaction temperature,emulsifier,initiator and functional monomer on emulsion performance were studied.The further researchs about emulsifier and modifying monomer were done by single factor experiments.The copolymer... |
