Recently, we have found a new class of step-growth radical polymerization of the designed monomer bearing a reactive carbon�halogen bond and an unconjugated carbon�carbon double bond in a single molecule, which is based on atom transfer radical addition similarly to controlled/living radical polymerization.In this paper, the step-growth radical polymerization was evolved into the systems for sequence-regulated vinyl polymer synthesis or simultaneous chain- and step-growth radical polymerization. The former is a novel strategy for preparing sequence-regulated vinyl copolymers by step-growth polymerization of sequence-regulated vinyl oligomers prepared from common vinyl monomers as building blocks, such as styrene, acrylate, acrylamide, acrylonitrile, and vinyl chloride Figure 1. <img src='https://acs-archive-assets2.s3.amazonaws.com/239nm/uploads/8020_gambierol.jpg' alt='' /> . In the later part, the simultaneous chain- and step-growth polymerization was investigated via the copolymerization of step-growth monomers with conjugated vinyl monomers, i.e., the step-polymerization was simultaneously compatibilized with the metal-catalyzed atom transfer radical polymerization. The combined polymerization resulted in the polymers with periodic functional moeities.
