| Abstract: | Aliphatic poly(cyclohexene carbonate),which has a T g of 120℃,was synthesized by coordinate-catalytical copolymerization of carbon dioxide and cyclohexene 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 (t 5% ,t 50% ) were 177℃ and 273℃, respectively. “End capping” can raise t 5% to 210℃.The copolymerization of CO 2, cyclohexene oxide (CHO) and phenyl isocyanate (PI) can increase the intrinsic viscosity ([η]) but decrease the T g. |
