摘要:通过原子自由基转移聚合的方法合成了一种大分子偶联剂 ,即苯乙烯、丙烯酸丁酯和 γ-甲基丙烯酸丙基三甲氧基硅烷的共聚物 ,其分子结构和分子量可控。这种大分子偶联剂用于云母的表面处理 ,能显著提高云母填充聚丙烯的力学性能 ,电镜观察表明大分子偶联剂有效地改善了云母与基体之间的界面结合。可以通过对大分子偶联剂分子结构的调节 ,实现对云母与基体界面结构和性能的控制 。
A macromolecular coupling agent was synthesized by atom transfer radical polymerization(ATRP) using styrene, n-butyl acrylate and γ-methacryloxypropyltrimethoxy silane, and its molecular structure and mass can be controlled. The surface treatment of mica by this macromolecular coupling agent significantly improved the mechanical properties of mica filled polypropylene, which can be attributed to the enhancement of interfacial adhesion between mica and matrix indicated by SEM observations. Furthermore, the structure and property of the interface between mica and matrix can be modified by adjusting the molecular structure of the macromolecular coupling agent, thereby adjusting the mechanical properties of mica filled polypropylene, to a certain limited extend.
