用茂金属Et(Ind)2ZrCl2和助催化剂MAO催化聚合了用甲氧基封端保护的侧链含氧原子的烯烃———[甲氧基-低聚(氧乙烯基)]-g-丙烯(MOP).用IR和1H-NMR表征了所得到的单体(MOP)和相应聚合物(PMOP).探讨了主要聚合条件对聚合反应的影响,以及PMOP与锂盐共混后的电导行为.研究表明,茂金属MAO可以催化用甲氧基封端保护的含氧原子烯烃的聚合,在MAO与Et(Ind)2ZrCl2物质的量比为1600,反应2h,60℃真空干燥后,该含氧乙烯基支链丙烯的聚合活性为8.2×104g(mol·h).氧乙烯基丙烯均聚物和甲氧基-低聚(聚氧乙烯)磺酸锂共混物的配比不同,其电导率在10-4.6～10-7.5S·cm-1之间.

The methoxyl\|oilgo(oxyethylene)\|g\|propylene (MOP) was polymerized by using Et(Ind)2ZrCl2 and metallocene. The main influencing factors on polymerization were investigated, and the monomer propylene (MOP) and the monomer propylene polymer (PMOP) were characterized as well. The electric conductivity of the blended PMOP with lithium salt was measured. As a result, the coefficient of polymerization activity is 8.2×10-4 g/mol·h when n(Al)/n(Zr) is equal to 1600 at 60 ℃ and reaction time of 2 hours. The conductivity of the blended PMOP is from 10-4.6 to 10-7.5 S/cm in different values of n(PMOP)/n(LiSEO7).
