Polyhomologation: The Living Polymerization of Ylides

Chemistry - A European Journal, 2000
The polymerization of dimethylsufoxonium methylide to produce linear polymethylene polymers is described. The reaction is catalyzed/initiated by trialkylboranes and gives organoboron star polymers as the primary product. The reaction is a living polymerization, providing control over molecular weight and functionality at the polymer chain ends.

From "Living" Carbocationic to "Living" Radical Polymerization

Journal of Macromolecular Science, Part A, 1994
Abstract “Living” carbocationic polymerization is compared to the “living” radical process. Similarities and differences are discussed. “Living” radical polymerization of vinyl acetate and methyl methacrylate to provide polymers with controlled molecular weights and narrow molecular weight distribution (Mw/Mn < 1.2) are presented.

Transformation of “living” carbocationic and other polymerizations to controlled/“living” radical polymerization

Macromolecular Symposia, 1998
AbstractTransformation of “living” carbocationic polymerization of styrene and isobutene to controlled atom transfer radical polymerization (ATRP) is described and formation of the corresponding AB and ABA block copolymers with styrene (St), methyl methacrylate (MMA, methyl acrylate (MA) and isobornyl acrylate (IBA) was demonstrated. A similar approach

Living and apparently living carbocationic polymerizations

Makromolekulare Chemie. Macromolecular Symposia, 1991
AbstractSome years ago, the occurrence of living carbocationic polymerization had not generally been expected to be possible, since it is well known that most carbocationic species are quite unstable and have very short lifetimes, and since transfer to monomer had been shown to be important, particularly near room temperature.

Living carbocationic polymerization

Polymer Bulletin, 1992
Living carbocationic polymerization of isobutylene (IB) was achieved by the 2-chloro-2,4,4-trimethylpentane (TMPCl)/TiCl 4 initiating systems in the presence of KCl in conjuction with the 18-crown-6 ether in CH 2 Cl 2 /hexanes solvent mixture at -80°C; The rate of initiation is relatively slow and the molecular weight distribution of the polymer ...
