Reaction Conditions

Reaction Steps

Into a reaction vessel, butyl acetate (40 g) was charged, and heating was made to 100° C. A mixture of methacryloyl isocyanate (7.5 g), methyl methacrylate (17.5 g), styrene (15.0 g), n-butyl acrylate (10.0 g) and 2,2'-azobis(2,4-dimethylvaleronitrile) (0.5 g) was dropwise added thereto in 2 hours. After stirring at 100° C. for 30 minutes, a solution of 2,2'-azobis(2,4-dimethylvalernoitrile) (0.25 g) in butyl acetate (10 g) was dropwise added thereto at 100° C. in 30 minutes, followed by stirring at 100° C. in 1.5 hours to give a copolymer of methcaryloyl isocyanate with methyl methacrylate, styrene and n-butyl acrylate. Number average molecular weight, 10,500. Non-volatile content, 42.3%. Viscosity (determined by Gardner bubble viscometer), K<<L.
