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℃.
