摘要

二氧化碳和环氧丙烷共聚物的玻璃化温度处于35～40℃

在低于20℃的环境下脆性很大.在稀土三元催化剂Y(CCl3COO)3ZnEt2甘油(glycerine)下实现了CO2、环氧丙烷(PO)和烯丙基缩水甘油醚(AGE)的三元共聚

合成了侧链带双键的二氧化碳共聚物

其玻璃化温度(Tg)为-15.4～36.1℃

大幅度拓展了二氧化碳共聚物的低温区使用范围.

Abstract

Functional CO2-based copolymem were synthcslzed by ccopolymerization of CO2

propylene oxide(PO) and allyl glycidvl ether (AGE) in the presence of rare ealth ternary catalyst Y (CCl3COO)3／ZnEt2／Glycerine．The yied and performance of the polymerization products were influenced by the molar ratio of PO and AGE．The CO2-based copolymers were characterized by IR(1747cm-1C=O；1240 cm-1C一O一C)

1H-NMR(δ=5.80～6.00(一CH一)

δ=5.15～5.30(=CH2))

13C-NMR(δ=134.50(—CH=)

δ=117.88(=CH2))

DSC and TGA.The results showedthat functional CO2-based copolymers with differentthermal properties could be pfepared by adjusfing the molar feed ratio of PO and AGE

and the glass transition temperature of products is adjustable from -15．4℃ to 36．1℃．
