ABSTRACT OF THE DISCLOSURE The invention relates to polyurethane-polyurea cellular elastomers having excellent energy absorbing pro- perties over a wide temperature range and at various impact speeds and, more particularly, to the production of such elastomers by reacting a polymer polyol, an aromatic polyamine and, an aromatic glycol with an organic poly- isocyanate. The elastomers are useful as energy absorbing components in automobile bumpers and the like.
