| Abstract: | Polystyrene and polystyrene-b-polyvinylacetate have been prepared in presence of either tetrathiophosphoric acidtri(1-phenylethyl) ester 1 or 1-phenylethyl-diphenylphosphinodithioate 2 under radical conditions. From kinetic studies performed with or without 1 or 2, it was shown that the polymerization presents the criteria of living/controlled polymerization. |
