Abstract
Acrylic polymers are made by the living radical polymerization of acrylic monomers utilizing organo halide initiators with either metal-free or metal catalysts. Moreover, block copolymers of vinyl halide monomers and acrylic monomers are described by generally polymerizing either the vinyl halide monomers or acrylic monomers utilizing an organo halide initiator in the presence of either a metal catalyst or a metal-free catalyst and subsequently polymerizing thereon the remaining type of monomer.
