Popis: The synthesis of acrylic polymers by free radical initiation is low cost and operable under easily obtainable conditions. It is the method of choice if one merely needs to obtain high-molecular-weight homopolymer and random copolymers from acrylic monomers. To obtain low-molecular-weight polymers and control polymer architecture one needs a living polymerization, i.e., one in which all the polymer chains grow simultaneously with no termination or chain transfer. Anionic polymerization and the related group transfer polymerization (GTP) are two such methods. This chapter gives a description of the GTP method, how it compares with anionic polymerization and other related methods, examples of polymer architectural control, mechanistic considerations, and synthetic procedures. A glossary at the end of the chapter gives the meanings of abbreviations and codes.
