3677 ABSTRACT OF THE DISCLOSURE Elastomeric polyurethane-polyurea polymers are disclosed that are derived from the reaction of organic polyisocyanates with A. primary hydroxyl polyols having a functionality of 2 to 4 and a molecular weight from 1500 to 12000, and B. extender mixtures comprised of 1.) an aromatic diamine wherein at least one of the positions ortho to each amine group is substituted by a lower alkyl group, and 2.) a low molecular weight diol, provided that the aromatic diamine comprises from 5 to 45 percent by weight of the extender mixture and the balance comprises the diol. The polymers find particular utility in the preparation of reaction injection molded parts, partic- ularly, automotive parts because of their excellent flexural modulus, tensile,and tear properties.
