反応手順
488 Parts of m-tetramethylxylene diisocyanate and 0.3 part of hydroquinone monomethyl ether were charged in a three necked flask and thereto was added dropwise a mixture of 295 parts of 2-hydroxypropyl methacrylate and 0.3 part of n-butyl tin dilaurate over a period of 3 hours at 60° C. with stirring. After completion of the addition, reaction was further allowed to proceed for 2 hours at 70° C., followed by cooling at 60° C. To the reaction mixture was added dropwise 426 parts of bis(diethoxyphenyl)sulfone over a period of 3 hours. After completion of the reaction, reaction was allowed to proceed for 5 hours at 70° C. to obtain urethane dimethacrylate (UDM2).
