Patent ID: 8242234

Claim:
A process for continuously manufacturing an amine functional epoxy resin, comprising (a) continuously adding reactants comprising polyepoxide, extender, and amine or amines selected from the group consisting of diisopropanolamine, dibutanolamine, diisobutanolamine, diglycolamine, methylethanolamine, aminoethylethanolamine, aminopropylmonomethylethanolamine, dimethylaminopropylamine, N,N-diethylaminopropylamine, dimethylaminoethylamine, N-aminoethylpiperazine, aminopropylmorpholine, tetramethyldipropylenetriamine, methylamine, ethylamine, dimethylamine, dibutylamine, dimethylaminobutylamine, diethylaminopropylamine, diethylaminobutylamine, dipropylamine, methylbutylamine, diketimine, and polyoxyalkylene amines to a reaction zone to prepare an amine functional epoxy resin by ring-opening polymerization, wherein the amine functional epoxy resin is a reaction product of the polyepoxide, extender and amine or amines wherein the amine functional epoxy resin continuously leaves the reaction zone at a rate equal to a combined rate at which all materials are added to the reaction zone.
