실험 절차
0.65 Mole of Sumiepoxy ELA-128 (an epoxy resin obtained by the reaction of bisphenol A with epichlorohydrin, epoxy equivalent 184-194; produced by Sumitomo Chemical Co., Ltd.), 0.17 g. of 2-methylhydroquinone and 1.3 moles of acrylic acid were successively charged into a 500 ml. four-necked flask, and the resulting mixture was sufficiently stirred. Further, 1.7 g. of triethylamine was added, and the mixture was heated to 110° C. while taking care of heat generation. The mixture was continuously stirred at said temperature for about 4 hours, and when the acid value had become less than 7, the reaction was completed. The reaction product was quickly cooled to about 60° C. and was incorporated and diluted with 0.066 g. of 2-methylhydroquinone and 133 g. of trimethylolpropane triacrylate to obtain a pale yellow, transparent liquid having a viscosity of Z6 to Z7 (as measured by use of the Gardener-Hodt Bubble viscometer at 25° C.). This liquid was named the compound (a).
