Reactive polyester-amide polymers as co-reactants or curing agents for polyepoxides and polyisocyanates

摘要

The reactive polyester-amide polymers of this invention are comprised of trihydric alcohols, aminoalcohols, and aliphatic dicarboxylic acids, containing an excess of functional groups reactive with carboxylic acid, and condensation heat-polymerized to an acid number of approximately 50.
