ABSTRACT:
Polymer/polyol compositions, obtained by polymerizing one or more ethylenically unsaturated monomers in situ in a blend of a polyether polyol and a polyamine, are of suitably high reactivity. The polymer/polyol compositions provide, by reaction with a polyisocyanate, polyurethanes having improved moldability and physical properties along with self-mold-release characteristics, and are particularly suitable for producing polyurethane by RIM process.
