含聚二甲基硅氧烷侧链的丙烯酸酯共聚物的研究

Synthesis and Properties of Poly(alkyl acrylate)-g-polydimethylsiloxane

摘要: 采用含活性基团的聚二甲基硅氧烷与丙烯酸酯进行自由基共聚合，合成了自聚二甲基硅氧烷侧链的丙烯酸酯共聚物。采用ＩＲ，＾１Ｈ－ＮＭＲ，ＧＰＣ等分析方法对共聚物结构和组成进行了表征。通过接触角和Ｘ－射线光电子能谱对共聚物的表面性能和表面组成进行了研究，并通过粘接性能和破坏面形貌对共聚物与金属铝材和加成型硅橡胶的粘接性进行了探讨。

Abstract: Poly (alkyl acrylate)-g-polydimethylsiloxane copolymers were prepared by using 3-(methacryloxy) propyl polydimethylsiloxane macromonomer. The structure and composition of the copolymers were characterized by FTIR, 1 H-NMR, GPC etc. The surface prope
