was sythesized by coordinate-catalytical copolymerization of carbon dioxide and cyclo-hexene oxide(CHO) with polymer-supported bimetallic catalyst (PBM) and was characterized by IR
NMR and DSC measurements.The thermal degradation of copolymers was studied by TG measurement
and found that 5% and 50% weight loss temperature (t5%
t50%) were 177℃
273℃
respectively.The copolymerization of CO2
cyclohexene oxide (CHO) and propylene oxide (PO) was also studied to evaluate the influence of mole percentage of cyclohexene oxide (CHO) on Tg."End capping"can raise t5% to 210℃.The copolymerization of CO2
cyclohexene oxide (CHO) and phenyl isocyanate (PI) can increase the intrinsic viscosity ([η])but decrease the Tg.
