以苯乙烯(St)、甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)和三乙二醇二甲基丙烯酸酯(TEGDMA)为原料,进行了四元共聚乳液的合成研究.红外光谱(FT-IR)和乳液物性的表征结果显示,合成得到了固含量为40％左右、贮存稳定的目标产物.用动态机械热分析仪(DMA)对聚合物胶膜的交联密度、阻尼性能和储能模量进行了表征,对胶膜的机械性能、耐热性能进行了测试.结果表明:共聚物的相关性能与其交联密度密切相关.共聚物的网链密度随TEGDMA用量的增加而增加;与线性胶膜相比,胶膜的耐热性能和储能模量均随网链密度的增加有较大提高;TEGDMA用量增加,胶膜机械性能得到改善,阻尼性能呈现先增后降的变化趋势.
