Mono azo compounds containing an acylating function

Abstract

Abstract (A) A CLASS OF AZO COMPOUNDS R-N =N-R1 WHERE R AND/OR R1 ARE GROUPS CONTAINING AN ACYLATING FUNCTION, E.G., ACYL CHLORIDE, CHLOROFORMATE OR ANHYDRIDE. EXAMPLE: CIS-4,4'',-AZOBIS-(4-CYANOVALERY CHLORIDE). (B) A CLASS OF AZO CONTAINING POLYMERS (R''-N=N-C(R2)(R2'')-R2"-Y)M-D-Z WHERE 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-4CYANOVALERY CHLORIDE AND HYDROXYL TERMINATED POLYBUTADIENE LIQUID RESIN. (C) A CLASS OF AZO CONTAINING POLYMER 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 ACYLREACTIVE 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.
