Title (EN) GAS PHASE POLYMERIZATION PROCESS
(FR) PROCEDE DE POLYMERISATION EN PHASE GAZEUSE
Abstract: front page image
(EN)The present invention relates to a process for preventing polymeragglomeration and for controlling the density of copolymer produced by an alpha-olefin copolymerization process in a polymerizationreactor, wherein the ratio of the flow rates of introduction of the comonomer(s) to the monomer is kept constant.
(FR)La présente invention concerne un procédé destiné à empêcher l'agglomération de polymères et à réguler la densité de copolymères produits par un procédé de copolymérisation alpha-oléfinique dans un réacteur de polymérisation, le ratio du débit d'introduction de comonomère(s) par rapport aux monomères étant maintenu constant.
