Polyurea polymers formed from polyethers having terminal amino groups

Abstract

Polyurea polymer compositions produced by reaction of isocyanates with compounds having terminal amino groups, said compounds being of the formula ##STR1## wherein z is 2 or 3, X is oxygen or sulfur and R stands for a z-valent group of the formula ##STR2## wherein k is 1 or 2, A is alkylidene or alkylated or non-alkylated vinylene, Y is B when k=1 and z=2; when k=2 and z=2; then Y is --CH.sub.2 --; when k=2 and z=3, then Y is ##STR3## and B in each case represents a divalent polyalkylene ether group or a polyalkylene thioether group such as is obtained by removal of the hydroxyl or mercapto groups from a polyalkylene ether diol or a polyalkylene thioether diol of a molecular weight of 100 to 15000. 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.
