Synthesis of Block Copolymers by Atom Transfer Radical Polymerization Li Hong (School of Environmental and Chemical Engineering, Shanghai University, Shanghai 201800) Abstract The progress in the synthesis of block copolymers such as hydrophobic block copolymers, amphiphilic block copolymers, functional block copolymers, fluorinated block copolymers, silicon- containing block copolymers and thermoplastic elastomers by atom transfer radical polymerization (ATRP) was introduced. The methods included (1) strict ATRP, which means block copolymers were generated from macroinitiators synthesized by ATRP， (2) mechanistic transformations, which means ATRP macroinitiators were prepared by other mechanism such as cationic, anionic, conventional radical and step growth polymerizations or a simple organic transformation.
