补充资料:乳胶IPN
分子式:
CAS号:

性质:又称乳胶IPN。是用乳液聚合的方法制得的IPN,是两个或两个以上聚合物网络在一个乳胶粒子上形成的互穿聚合物。将交联的聚合物I作成“种子”胶粒,加入单体2,同时加入交联剂和引发剂(但不再加入乳化剂),使单体2在聚合物I所形成的“种子”胶粒的表面进行聚合和交联。因为互穿网络仅限于各个乳胶粒子范围之内,所以也称为微观IPN。这种IPN乳胶粒子具有核-壳结构,其具体形态受下列因素的共同影响:单体的加入方式、单体1及2、聚合物I及II之间的混容性、配料比、引发剂类型、聚合物I、单体2、聚合物II相对亲水性的大小等。根据这些参数的不同可以生成各种不同的形态结构。乳胶互穿网络聚合物在力学性能上一般表现出明显的协同效应,有良好的综合机械性能,常见的几种类型有聚甲基丙烯酸酯类/聚丙烯酸酯类乳胶IPN、丁苯橡胶/聚丙烯酸酯类乳胶IPN、PVC/NBR乳胶IPN等。乳胶IPN可以乳液的形式直接使用,也可以凝析成固态粉末物料再加工成型各种产品,在塑料改性、橡胶增强、涂料、黏合剂、阻尼材料及医用高分子领域得到广泛应用,如多层结构的丙烯酸酯乳胶IPN用作地毯底衬、黏合剂;PVC/P(B-AN)用于阻尼涂料等。
