“…11 NMR investigations on model compounds at ambient temperature suggest that beside cyclization a second termination reaction is observed. Hofmann elimination and methylation were obtained by Bandermann et al 12,13 in the polymerization of MMA in THF with tetrabutyl-and tetramethylammonium malonates, respectively. Thus, in conjunction with increasing backbiting termination, the molecular weight distributions of the obtained polymers broaden (M w /M n > 1.5).…”

The polymerization of n-butyl acrylate initiated by ester enolates in the presence of tetraalkylammonium halide−trialkylaluminum complexes, R4N[Al n R‘3 n X] (n = 1, 2), in toluene has a controlled character at −78 °C only for selected combinations of the complex. Quantitative monomer conversions are usually reached with Me4N[Al n Bui 3 n Cl] leading to polymers with narrow molecular weight distributions (M w/M n < 1.2). Kinetic investigations show a complex mechanism of the polymerization, implying an equilibrium between at least two active species. Besides, various acrylate homopolymers and block copolymers (PMMA-b-polyacrylate) can be synthesized with this new initiating system.

A tetramethylammonium (TMA)–triphenylmethide (TPM) initiator generated in situ by the reaction of trimethyltriphenylmethylsilane with tetramethylammonium fluoride in tetrahydrofuran was found to have greater stability than the corresponding tetrabutylammonium or tetrahexylammonium derivatives. The predominant mode of degradation of TMA–TPM was found to be the TMA‐mediated methylation of TPM anions. The initiation of methyl methacrylate by TMA–TPM in tetrahydrofuran at −78 °C was demonstrated to produce quantitative yields of poly(methyl methacrylate) with polydispersities of less than 1.1. Although the initiator efficiencies were low (9–40%) because of relatively slow initiation on the polymerization timescale, the initiation appeared to be rapid enough to give relatively narrow molecular weight distributions. © 2003 Wiley Periodicals, Inc.
