ABSTRACTThe metal-catalyzed step-growth radical polymerization was achieved to enable two systems for preparing tailored polymeric structures, i.e., sequence-regulated vinyl copolymer and periodically-functionalized polymer. The former is a novel strategy for preparing sequence-regulated vinyl copolymers by step-polymerization of sequence-regulated vinyl oligomers prepared from common vinyl monomers as building blocks. The later deals the simultaneous chain- and step-growth radical polymerization, which resulted in the polymers with periodic functional groups.

Metal Catalyzed

Metal-catalyzed simultaneous chain- and step-growth radical polymerization was examined to combine common conjugated vinyl monomers, such as various acrylates and styrene, as chain-growth monomers and various ester- or amide-linked monomers bearing both an unconjugated C=C bond and an active C–Cl bond as step-growth monomers. The CuCl/1,1,4,7,10,10-hexamethyltriethylenetetramine-catalyzed copolymerization of alkyl acrylates and various step-growth monomers at a 1 : 1-monomer feed ratio resulted in almost linear random copolymers that consisted of vinyl polymer and polyester units. Additional functional groups, such as oxyethylene and disulfide units, can be introduced into the main chain using a step-growth monomer that possesses the functional units between the unconjugated C=C bond and the active C–Cl bond. Copolymerization at a higher feed ratio of chain-growth monomers, such as alkyl acrylates and styrene, can provide multiblock vinyl polymers connected to the functionalized step-growth monomer units.
