Abstract
Reaction injection molded (RIM) elastomers are made in a one-shot process from certain aromatic-amine amides which comprise the reaction product of a polyoxyalkylene polyamine selected from the group consisting of diamines, triamines and mixtures thereof, and having an average molecular weight of above about 3000 and an isatoic anhydride of the formula: ##STR1## where R is selected from the group consisting of hydrogen, alkyl, nitro, halo, hydroxy, amino and cyano and n is a number of 1-4. Such elastomers have improved tensile strength, tear strength and elongation properties.
