Abstract: In this paper,kinetic behavior of the group transfer polymerization of ethyl acrylate initiated directly with triphenyl-phosphine and trimethylchlor-silane was studied by means of 31P NMR and 1H NMR kinetic spectra.Elementary reaction of initiating step,chain adding step and chain stopping of this GTP reaction was investigated.Kinetic behavior of conjuated addition of TPP to EA and catalytic action of zinc bromide in this initiation system were discussed.GTP reaction process history in this new initiating system was also proposed.

Key words: Group transfer polymerization (GTP), Trimethylchlorosilane (TMCS), Ethylacrylate (EA), 1H NMR kinetic spectra, 31P NMR kinetic spectra
