Reaction Steps
244 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 302 parts of 2-hydroxypropyl methacrylate and 0.3 part of n-butyl tin dilaurate over a period of 3 hours with stirring at 60° C. After completion of the addition, reaction was allowed to proceed for 8 hours at 70° C. to obtain urethane dimethacrylate UDM1.
