Title (EN) PROCESS FOR PREPARING ETHYLENE (CO) POLYMERS
(FR) PROCEDE DE PREPARATION DE (CO)POLYMERES D’ETHYLENE
Abstract: front page image
(EN)For the (co) polymerization of ethylene with other 1-olefins, a Ziegler catalyst which comprises the product from the reaction of a magnesium alkoxide suspended or dispersed as ge in an inert solvent with a tetravalent transition metal compound and is subjected to a thermal after-treatment for a period of not more than 180 minutes is prepared. The catalyst gives a high yield of a polymer powder which has a broad molar mass distribution and is best suited to the production of films, hollow bodies and pipes.
(FR)L’invention concerne la (co)polymérisation de l’éthylène avec d’autres 1-oléfines pour laquelle on prépare un catalyseur Ziegler contenant le produit issu de la réaction d’un alcoxyde de magnésium suspendu ou dispersé sous forme Ge dans un solvant inerte avec un composé à base de métal de transition tétravalent et est soumis à un post-traitement thermique durant une période inférieure à 180 minutes. Le catalyseur produit une grande quantité de poudre de polymère possédant une distribution de masse molaire importante et mieux adaptée à la production de films, de corps creux et de tuyaux.
