Procedure

100 parts of hydrogenated polyisoprene glycol (PIP-H, average molecular weight of 2500, made by Idemitsu Petrochemicals Corp. Japan), 9 parts of epichlorohydrin, 0.15 part of trifluoroborondiethylether complex and 50 parts of toluene were fed and carried out addition reaction under vigorous stirring at 55 degrees C. for 5 hours in the nitrogen atmosphere. Then, 9.5 parts of 48% aqueous solution of sodium hydroxide were added and a ring-closing reaction was carried out at 65 degrees C. for 5 hours. After the reaction 100 parts of water were added and the following procedures were carried out same as described in Reference Example No. 1 and 95 parts of glycidyl ether of hydrogenated polyisoprene glycol (b) were obtained. The glycidyl ether (b) had an epoxy equivalent weight of 1,430 g/eq.
