Abstract
L'invention concerne un procédé de régulation de la rhéologie de résines et un catalyseur pour sa mise en oeuvre. On utilise un catalyseur constitué par un support poreux sur lequel se trouvent en enduits des composés du chrome et de l'aluminium, le support présentant une teneur en humidité régularisée. Les résines de polyoléfines obtenues présentent une réponse rhéologique qui est contrôlée.The invention relates to a process for regulating the rheology of resins and to a catalyst for its implementation. A catalyst is used consisting of a porous support on which chromium and aluminum compounds are coated, the support having a regulated humidity content. The polyolefin resins obtained exhibit a rheological response which is controlled.
