【摘要】 <正>遥爪低聚物是指链末端带有反应性官能团的低聚物,分子量在5000至15000之间。利用遥爪低聚物的活性官能团与其它聚合物反应,可对聚合物进行改性。因为遥爪低聚物结构的不同,改性高聚物的结构可以呈现多样性,从而进行高聚物的分子设计,满足对材料的要求。本文采用常压惰性气氛阴离子聚合法,用正丁基锂为引发剂(自制),乙二醇二缩水甘油醚为封端剂,合成了末端带有环氧基团的聚苯乙烯遥爪低聚物,并对其结构和性能进行了更多还原

【Abstract】 Epoxy ether terminated polystyrene oligomer, whose molecular weight was about 5000, was prepared by reaction of the polystyrene onions with glycol diglycidly ether. The oligomer was characterized by GPC、IR and 1H-NMR. The reaction time, temperature of termination and the terminator consumption were taken into account. The results show that the termination efficiency is tiptop when the temperature and time are increased, and the mole ratio of glycol-diglycidyl ether and n-BuLi equals 4:1 is better.更多还原
