Systems and Methods for Fabricating Polymers

摘要

The present invention is broadly directed to various methods and systems for gas and liquid phase polymer production. In certain embodiments, the methods are performed in conjunction with a polymerization reactor system such as gas phase reactor system or liquid phase reactor system. The invention is also broadly directed to various systems in which polymer properties are manipulated by addition of DEALE directly to a polymerization reactor system.

主权项

1. A method for producing a polymer, comprising:
injecting a chromium oxide-based catalyst into a gas phase reactor system; contacting a gaseous monomer with the catalyst in the reactor system for polymerizing the monomer to form a polymer; and adding an alkyl aluminum alkoxide in situ to the reactor system in an effective amount for reducing a molecular weight of the polymer to about a target molecular weight.
