Abstract
Copolymers of glycidyl methacrylate (GMA) and N-benzyl-N-[2-(methacryloglyoxy)ethyl]N,N-dimethylammonium bromide (1b) were synthesized by radical copolymerization in acetonitrile using AIBN as an initiator to obtain copolymer-6 (GMA:1b=94:6) and copolymer-10 (GMA:1b=90:10), respectively. When copolymer-6 was reacted with CO 2 at 100°C in NMP for 24 h, 86% of the epoxide group was converted to the five-membered cyclic carbonate moiety by self-catalyzation. When the powder of copolymer-6 was exposed to CO 2 under an atmospheric pressure at 140°C for 500 min, incorporation of CO 2 into copolymer-6 was attained up to 76%
