Abstract
Abstract(2‐Oxo‐1,3‐dioxolan‐4‐yl)methyl methacrylate (6) was prepared by fixation of CO2 into glycidylSystematic 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 hydroxyurethaneThe 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.
