Abstract

Process for the synthesis of block polymers, homopolymers and copolymers of narrow polydispersity having formula (1) by contacting selected vinyl monomer(s), vinyl-terminated compound(s) and free radicals in which effective control of production of polymer is achieved by controlling the mole ratio of vinyl monomer(s), vinyl-terminated compound(s) and free radicals relative to one another; and polymers produced thereby ##STR1##
