Ylide mediated polymerization of methacrylates and acrylates in the presence of tetraphenylphosphonium cation 3
Authors:Angela P. Zagala  Dimo Dimov  Thieo E. Hogen-Esch
Abstract:Triphenylmethide tetraphenylphosphonium (TPM, TPP) or methylisobutyrate tetraphenylphosphonium (MIB, TPP) formed by ion exchange reactions of TPP chloride(TPPCl) with the TPM or MB potassium salts in THF, initiate the living polymerization of MMA producing PMMA's with narrow MW distributions (below 1.3) at ambient temperatures.
Keywords:Ester enolates  phosphorylides  anionic polymerization  living polymerization  methacrylates
