実験手順

100 Parts of polyesterdiol which was formed from butanediol and adipic acid and had a molecular weight of about 1,000, 75 parts of diphenylmethane diisocyanate and 0.1 part of dibutyltin dilaurate were mixed, and the resultant mixture was allowed to react at 50° C. for 30 minutes and at 90° C. for 2 hours, and the reaction mixture was cooled to 70° C. Then, 26 parts of 2-hydroxyethyl methacrylate was added, and further, the resultant mixture was allowed to react for 3 hours to give urethane dimethacrylate.
