Abstract
A thermosettable polyaminoester composition useful as a plastic, coating, resin modifier, and elastomer is provided. The thermosettable polyaminoester is formed by reacting one or more acrylic or methacrylic terminated polyalkylene maleate or fumarate oligomers with one or more polyamines and optionally with one or more alpha, beta-ethylenically unsaturated monomers. The composition is especially useful in the RIM process.
