Reaction Steps
A mixture of 2-isopropenyloxazoline-4,5-dione hydrochloride (15 g), methyl methacrylate (20 g), n-butyl acrylate (15 g), 2,2'-azobis(2,4-dimethylvaleronitrile) (1.25 g) and ethyl acetate (25 g) was dropwise added to toluene (50 g) heated at 100° C. in 90 minutes while stirring. Stirring was further continued for 5 hours, whereby a copolymer of methacryloyl isocyanate with methyl methacrylate and n-butyl acrylate was produced. Viscosity, C-D (determined by Gardner bubble viscometer). Non-volatile content, 40%. Mw, 7100 (determined by gel permeation chromatography).
