초록 ▼

Non-gelled compositions containing hydroxy ester copolymer having carboxyl groups and substantially free of oxirane groups and the method of making them are disclosed which are the esterification reaction product of (A) acidic addition copolymer; and (B) epoxy resin including aromatic polyether containing oxirane groups in which the epoxy resin comprises at least 40% of the total resin solids and contains insufficient oxirane groups to react with all of the carboxyl groups in the copolymer; in which esterification is conducted in the presence of higher than the normal amount of amine catalyst, i.e., 1.5% or more. The resulting composition is neutralized with amine, is self-emulsifiable in water and is useful for coatings, e.g., for cans.

대표청구항 ▼

A method of esterifying a solvent-soluble carboxyl-functional polymer with an epoxy resin without gelation which comprises conducting the esterification reaction in organic solvent medium in the presence of greater than about 1.5% based on the weight of the reactants subjected to esterification, of an amine esterification catalyst and at an elevated temperature sufficient to cause the oxirane groups of said epoxy resin to react with said carboxyl groups until said oxirane groups are substantially entirely consumed; in which said epoxy resin comprises aromatic polyethers containing oxirane groups, at least 5% of said aromatic polyethers being diepoxide, said epoxy resin constituting at least about 40% of the total resin solids content and containing sufficient oxirane groups to provide a ratio of oxirane groups to carboxyl groups of from 1:2 to 1:20 to produce an epoxy resin-carboxyl polymer ester, the improvement comprising: dispersing said epoxy resin-carboxyl polymer ester in an organic medium of organic solvent.
