Abstract
The invention is directed to polymers containing thiuram disulfide groups and their preparation. These polymers are iniferters in radical polymerization of vinyl monomers. Macroiniferters (having one thiuram disulfide group in their main chain) and polyiniferters (having more than one thiuram disulfide group in their main chain) result respectively, in triblock copolymers PA--PB--PA and diblock copolymers. --PA--PB).sub.z, z having a value from 2 to 25.
