METHODS FOR CONTROLLING DIE SWELL IN DUAL CATALYST OLEFIN POLYMERIZATION SYSTEMS
摘要
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.
