(FR) PROCEDE DE SYNTHESE DE POLYMERES A BLOCS PAR POLYMERISATION RADICALAIRE CONTROLEE EN PRESENCE D'UN COMPOSE DISULFURE
Abstract
(EN)
The invention concerns a method for preparing a first generation polymer comprising a step which consists in radical polymerisation of a composition containing: at least an ethylenically unsaturated monomer, a free radical source, at least a compound (I) of general formula (IA) or (IB), a compound of formula (II).
