摘要
聚-4-甲基戊烯-1(PMP)是一种半结晶性高聚物,主链结构为饱和碳-碳链,由于其大侧基的存在,高分子链间间隙较大,利于气体分子的扩散,因而其均质膜对氧气的透过系数比同样是碳-碳主链的聚乙烯约高一个数量级。 PMP有较高的强度,但在室温下很难溶于一般烃类溶剂中,前文已报道,在PMP结构中引入电负性较大的溴原子后明显地改善了其在有机烃类溶剂中的溶解性。 然而,
Bromo- and chloropoly-4-methylpentene-l were obtained from the macromolecular reactions of PMP with chlorine and bromine respectively. The influences of reaction conditions, the contents of bromine and chlorine in halo-PMP and the natures of bromine and chlorine themselves on the gas permeation properties were discussed.
