Title
(EN) PROCESS FOR PREPARING PROPYLENE POLYMERS HAVING LONG CHAIN BRANCHES
(FR) PROCÉDÉ DE PRÉPARATION DE POLYMÈRES DE PROPYLÈNE AYANT DES RAMIFICATIONS À LONGUE CHAÎNE
Abstract
(EN) The present invention relates to a process for the preparation of long chain branched propylene polymers via a polymerization of propylene, preferably under slurry or bulk conditions, in the presence of a catalyst system comprising a supported bridged metallocene catalyst and at least one alpha,omega-diene compound. The invention moreover relates to long chain branched propylene polymers obtained by the present process.
(FR) La présente invention concerne un procédé de préparation de polymères de propylène ramifiés à longue chaîne par l'intermédiaire d'une polymérisation de propylène, de préférence en suspension ou en vrac, en présence d'un système catalyseur comprenant un catalyseur métallocène ponté supporté et au moins un composé alpha,oméga-diène. L'invention concerne en outre des polymères de propylène ramifiés à longue chaîne obtenus par le présent procédé.
