Abstract:
1. A method of use of a heat-stable polymer comprising: blending the heat-stable polymer with one or more other polymers to create a polymer blend that is more durable than the one or more other polymers; and incorporating the polymer blend into an article of manufacture to make a durable article of manufacture; wherein the heat-stable polymer has repeating units of formula 1 or 2; wherein one of R the other of R each R each R X is a bivalent radical of from 1-100 atoms, and p is 0 or 1; any alkyl or phenyl can optionally be substituted with one or more halo, hydroxy, nitro, mercapto, cyano, (C wherein the repeating units of formula 1 or 2 comprise 0.1 to 65% by weight of the polymer blend; and wherein the one or more other polymers comprise polyisobutylene, polyethylene, or polypropylene.
