Abstract

Abstract A. A novel class of azo compounds R-N═N-R 1 where R and/or R 1 are groups containing an acylating function, e.g., acyl chloride, chloroformate or anhydride. Example: Cis-4,4'-Azobis-(4-cyanovaleryl chloride). B. a novel class of azo containing polymers (R'--N═N--C(R.sub.2)(R.sub.2 ') --R.sub.2 "--Y).sub.m --E--(Z).sub.n wherein R' is t-aliphatic, formed by reacting a polymer having at least one group reactive with an acyl group and a compound as in "A" containing only one acylating function. Example: the reaction product of 4-t-butylazo-4-cyanovaleryl chloride and hydroxyl terminated polybutadiene liquid resin. C. a novel class of azo containing polymers Z(E--Y--R.sub.2 "--C(R.sub.2)(R.sub.2 ')--N═N--C(R.sub.2)(R.sub.2 ')--R 2 "--Y) m' --E--Z, formed by the reaction of a compound as in "A" having two acylating functions with (1) a monomer having two acyl-reactive groups and a monomer having two acylating functions, or (2) a polymer having at least one acyl-reactive group. D. polymers B and C are useful in the production of block and graft polymers and in curing unsaturated polyester resin-vinyl monomer systems. Polymer C forms block and graft polymers with vinyl monomers with substantially no formation of homopolymers. These block and graft polymers are compatibilizing agents for solutions of homopolymers.
