补充资料:多组分接枝共聚物
分子式:
CAS号:
性质:三个或三个以上相同或不同类型的聚合物接枝共聚的产物。由于每一组分可能都有自己独立的相,所以具有多相结构,因此也可视为一种混合物。例如将交联聚乙烯和聚丙烯酸钾接枝,然后用苯乙烯溶胀进行辐射聚合,可以得到三元接枝共聚物的半-IPN。又如将丙烯酸正丁酯、苯乙烯、单丙烯酸1,4-丁二醇酯和二丙烯酸1,4-丁二醇酯用乳液聚合形成聚合物I,再分别将丙烯酸正丁酯、苯乙烯和丙烯酸用乳液聚合形成聚合物Ⅱ;将二者混合、沉淀、洗涤、干燥并溶于苯乙烯和丙烯酸中,随后进行聚合形成聚合物III。把材料加热,即能在聚合物Ⅰ和Ⅱ或Ⅰ和III之间引发接枝。简单说来,聚合物Ⅰ是交联SBR,聚合物Ⅱ是交联苯乙烯—甲基丙烯酸甲酯共聚物,聚合物III是交联聚甲基丙烯酸甲酯。把这些聚合物相继合成为乳胶粒子,然后将这些乳胶材料和线型聚氯乙烯机械共混。最后,把四种聚合物混在一起,每一种都有不同的玻璃化转变温度。
