Title: Modified epoxy resin
Inventor: WATANABE MASAHARU
IPC: C08G59/00
Filed: 1981-04-03
Abstract: PURPOSE: A prim. hydroxyl group-containing modified epoxy resin having excellent flexibility and excellent reactivity with a crosslinking agent, prepared by a ring opening polymerization of ε-caprolactone and the hydroxyl groups of an epoxy resin.  
     CONSTITUTION: A prim. hydroxyl group-containing moldified epoxy resin having excellent flexibility and excellent reactivity with a crosslinking agent is prepared by reacting 3W95pts.wt. ε-caprolactone with 97W5pts.wt. hydroxyl group- containing epoxy resin to subject ε-caprolactone and the sec. hydroxyl groups of the epoxy resin to a ring opening polymerization. Heretofore,a hydroxy group- containing epoxy resin has had a drawback that because its hydroxyl groups are secondary, the reactivity with a crosslinking agent is poor, high temperatures are required for baking crosslinking and the weather resistance is poor. However, by this ring opening polymerization of ε-caprolactone, appropriate flexibility is obtained, the hydroxyl groups are converted into highly reactive prim. hydroxyl groups and the reaction with a crosslinking agent is facilitated.
