ABSTRACT:
Compounds which comprise an azo group linking an aliphatic group to an olefin-bearing aromatic group, for example t-butylazostyrene, can be polymerized at temperatures of 130.degree. C. or more without causing substantial thermal decomposition of the azo group. The compounds and their polymers may be stored indefinitely at ambient temperatures. The azo group in the polymer will decompose at temperatures in excess of 240.degree. C. to become a free radical initiator or cross-linking agent.
