Title (EN) PROCESS FOR THE PREPARATION OF BLOCK COPOLYMERS
(FR) PROCEDE DE PREPARATION DE COPOLYMERES SEQUENCES
Abstract: front page image
(EN)Process for the preparation of block copolymers, based on vinylaromatic monomers and monomers deriving from (meth)acrylic acid by means of radicalic polymerization which comprises polymerizing the monomers at a temperature higher than or equal to 120°C, in the presence of a radicalic initiating system comprising a compound having general Formula (I).
(FR)L'invention concerne un procédé de préparation de copolymères séquencés à base de monomères vinylaromatiques et de monomères dérivés de l'acide (méth)acrylique par une polymérisation radicalaire qui comporte la polymérisation des monomères à une température supérieure ou égale à 120 °C en présence d'un système initiateur radicalaire comportant un composé de la formule générale (I).
