Living carbocationic polymerization
Polymer Bulletin, 1988Summary Rapid living carbocationic polymerization of p-methylstyrene pMeSt is readily induced by a variety of esters i.e., cumyl acetate (CumOAc), cumyl propionate (CumOPr), l(2,4,6trimethylphenyl)ethyl acetate (TMePhEtOAc) and l(4-methylphenyl)ethyl acetate (pMePhEtOAc) in the presence of BC~ in CHIC1 and C2HsCI solvents at -30 ~ and -50~ using both ...

Photocontrolled living polymerizations
Nature Materials, 2006Living polymerizations involve the creation of polymer chains without significant irreversible chain transfer or chain termination. Such processes are widely used to access well-defined macromolecular materials with controlled architectures, such as block and star polymers.

Living carbocationic polymerization. 55. Living polymerization of indene
Macromolecules, 1993The cationic polymerization of indene (In) has been investigated using the 2-chloro-2,4,4- trimethylpentane (TMPCl)/TiCl 4 initiating system and a methyl chloride-methylcyclohexane solvent mixture at -80°C. According to kinetic studies, initiation is slow relative to propagation.

Living carbocationic polymerization. IV. Living polymerization of isobutylene
Journal of Polymer Science Part A: Polymer Chemistry, 1987AbstractTruly living polymerization of isobutylene (IB) has been achieved for the first time by the use of new initiating systems comprising organic acetate‐BCl3 complexes under conventional laboratory conditions in various solvents from −10 to −50°C.

Toward Living Radical Polymerization
Accounts of Chemical Research, 2008Radical polymerization is one of the most widely used processes for the commercial production of high-molecular-weight polymers. The main factors responsible for the preeminent position of radical polymerization are the ability to polymerize a wide array of monomers, tolerance of unprotected functionality in monomer and solvent, and compatibility with ...

Living carbocationic polymerization
Polymer Bulletin, 1994The effect of various new electron donors (EDs), specifically esters (dimethyl phthalate, di-t-octyl phthalate, methyl benzoate, ethyl isobutyrate, dimethyl 3,3-dimethylglutarate, dimethyl terephthalate, dimethyl 5-t-butylisophthalate, trimethyl 1,3,5-benzenetricarboxylate) and ketones (acetophenone and benzophenone), on the living cationic ...

Current Opinion in Solid State and Materials Science, 1999
For about 40 years living anionic polymerization has been the premier technique for the synthesis of model polymers of controlled architecture and narrow molecular weight distribution (MWD). Nowadays, despite the continuing development of new strategies for the synthesis of well-defined polymers and copolymers (e.g.

Science, 1991
Living polymerization techniques can be used to achieve a high degree of control over polymer chain architecture. Examples of the type of polymers that can be synthesized include block copolymers, comb-shaped polymers, multiarmed polymers, ladder polymers, and cyclic polymers.
