METHODS FOR CONTROLLING DIE SWELL IN DUAL CATALYST OLEFIN POLYMERIZATION SYSTEMS

Methods for controlling the die swell of an olefin polymer produced using a dual catalyst system are disclosed. The die swell of the olefin polymer can be increased or decreased as a function of the catalyst weight ratio and the reactant molar ratio used during the olefin polymerization process. L&#...

Summary:Methods for controlling the die swell of an olefin polymer produced using a dual catalyst system are disclosed. The die swell of the olefin polymer can be increased or decreased as a function of the catalyst weight ratio and the reactant molar ratio used during the olefin polymerization process. L'invention concerne des procédés de commande du gonflement à la filière d'un polymère oléfinique produit à l'aide d'un système à double catalyseur. Le gonflement à la filière du polymère oléfinique peut être augmenté ou diminué en fonction du rapport en poids de catalyseur et du rapport molaire de réactif utilisé pendant le processus de polymérisation d'oléfines.
