Abstract

Novel elastomers are provided of the formula:

WHEREIN R1, R2 and R3 are independently selected from aryl and alkyl of 1 to 10 carbon atoms; X is a polymethylene chain of from 2 to 10 carbon atoms; Y is a group selected from ureido, silylureido, amido, silyamino, thioureido, silylthioureido, urethane alkylideneamino, isocyanoureido, halosilylamino and sulfonamido; Z is a hydrocarbon of from 1 to 50 carbon atoms selected from alkyl, alkaryl, aryl, aralkyl which hydrocarbon can be substituted with one or more groups selected from hydroxy, nitro, halo, sulfonamido and carboxyl; m and n are integers wherein the ratio of m:n is between 20:1 and 1000:1, and p is an integer from 1 to 3.
