| 摘 要： | 研究了环氧乙烷(EO)与烯丙基缩水甘油醚(AGE)以双金属氧联醇盐为催化剂的共聚条件对转化率及共聚物[η]的影响。结果表明AGE占10％时共聚转化率可达90％,[η]可达150ml/g。产物经IR及~1HNMR表征,用偏光显微镜、DSC及广角X射线衍射研究其结晶性,并研究了该共聚物与LiCIO_4络合物的导电率其与结晶度的关系,指出在PEO占70％、EO/Li=20时,络合物的室温导电率接近10~(-4)s/cm。

| Abstract: | Copolymerization of ethylene oxide (EO) with allyl glycidyl ether (AGE) in toluene using bimetallic-oxoalkoxide as catalyst was studied. The results showed that conversion can reach 90% when 10%AGE was used. Crystalline behavior of the copolymer was investigated by polarized microscopy,DSC and wide angle X-ray diffraction. Room temperature conductivity of the copolymer complexed with UClO4 approached 10-4s/cm for the copolymer with 70% PEO and EO/Li=20. |
