Abstract (2‐Oxo‐1,3‐dioxolan‐4‐yl)methyl methacrylate ( 6 ) was prepared by fixation of CO 2 into glycidyl Systematic name: 2,3‐epoxypropyl. methacrylate (2) . Pure 6 polymerized spontaneously at room temperature. Radical polymerization of 6 (purity 94%) was carried out at 60°C using 2,2′‐azoisobutyronitrile as an initiator in dimethyl sulfoxide (DMSO) to give the corresponding homopolymer 1 (yield: 99%) which is soluble in DMSO and N , N ‐dimethylformamide. 1 was reacted with butylamien at room temperature in DMSO for 24 h to the corresponding polymethacrylate 13 (yield: 100%) having a hydroxyurethane The systematic name for urethanes is carbamates. group in the side chain. No reaction of the ester groups of 1 with butylamine was observed. This was also demonstrated by the model reaction of (2‐oxo‐1,3‐dioxolan‐4‐yl)methyl isobutyrate (9) with butylamine in which the corresponding hydroxyurethanes 10 , 11 and 12 were isolated in 96% yield.
