ABSTRACT:
Moldable energy absorbing rigid polyurethane foams are prepared by reacting a polyoxyalkylene polyether polyol containing therein a graft polymer dispersion, an alkylene oxide adduct of an aromatic amine in the presence of a crosslinking agent with an organic polyisocyanate. Alternatively, the aromatic amine may be replaced with an alkylene oxide adduct of pentaerythritol, ethylenediamine, .alpha.-methylglucoside, sorbitol and sucrose. The products are useful in various automobile body parts.
