Azoinitiatoren, 10. Co- und terpolymerisation von butadien und styrol mit phenyl(3-vinylphenylazo)sulfid

Phenyl(3-vinylphenylazo)sulfide ( 2 )—displaying not only the properties of an initiator (thermolysis) and a monomer (vinyl group) but also of a chain transfer agent (sulfenyl group)–was copolymerized with styrene in emulsion at 40°C and in bulk at 50°C. Terpolymerization with styrene and butadiene at 5°C in emulsion led to azo-containing unsaturated polymers, which could be used for self crosslinking.
