简介：penta醚混合物被di(trimethylolpropane)的反应作为烷基卤化物作为强壮的底和甲基碘化物与钠氢化物综合。这混合物被NMR，FTIR，和GC技术描绘。MgCl2-supported钛催化剂与作为内部施主改变penta醚化合物的数量被合并，也，没有内部施主的催化剂被综合。综合催化剂和常规Ziegler-Natta催化剂被描绘。钛内容被spectrophotometry决定，由由argentometric滴定的complexometric滴定和氯化物的镁。有准备MgCl2-supportedZiegler-Natta催化剂的丙烯聚合上的新内部施主的效果被调查然后这些结果与用常规diisobutylphthalate-besed-Ziegler-Natta催化剂获得的结果相比。聚丙烯的最高的crystallinity度，融化的温度，和isotacticity与penta-ether/Mg用催化剂被获得臼齿的比率平等者到0.21。
