Abstract

Abstract Polyurea polymer compositions produced by the isocyanate polyaddition process by reacting compounds having terminal groups and represented by the general formula: ##STR1## wherein z is an integer of 2 to 4, X is oxygen or sulfur and R is a group of the formula: -Y-[Ar-B].sub.k wherein k is an integer of 1 to 4, Ar is an aromatic group, Y is B when k is 1 and when k is 2, then Y is an alkylidene group having 1 to 5 carbon atoms and B represents a divalent polyalkylene ether group or polyalkylene thioether group such as is obtained by the removal of the hydroxyl or mercapto groups from a polyalkylene ether diol or a polyalkylene thioether diol of a molecular weight of about 100 to 15000, with a polyisocyanate. The polymer compositions are useful for the formation of vehicle tires of all types and for the formation of portions of vehicle wheels, for belts, fasteners and shoe soles.
