Stereoregulation of Homogeneous Free Radical, Cationic and Anionic Polymerization Reactions

摘要: The preceding discussions have been concerned almost entirely with the sterochemical control and formation of stereoregular polymers by heterogeneous catalysts, presumably at chiral active sites on catalyst surface. This chapter is homogeneous reactions, primarily ionic polymerization in which endgroup freely accessible a matrix solvent molecules. not necessarily passive, indeed except for free radical reactions (for specific effects stereochemistry has yet convincingly demonstrated) carbanions (but probably carbenium ions), solvation can play very important role propagation.
