| Abstract: | Aliphatic poly(styrene carbonate) was sytbesized by coordinate - catalytical copolymer- ization of carbon dioxide and styrene oxide(StO) with polymer - supported bimetallic catalysts (PBM) and was characterized with IR, 1 HNMR and DSC. The thermal degradation of copolymers was studied by TG and found that 5 % and 50% weight loss temperature (t5%, t50% ) were 218℃and 271 ℃ respectively. |
