Title:
【発明の名称】プロピレンホモポリマーもしくはコポリマーを製造する方法
Document Type and Number:
Japanese Patent JP2002501549
Kind Code:
A
Abstract:
A process for homo or copolymerizing propylene, wherein propylene is polymerized in the presence of a catalyst at an elevated temperature in a reaction medium in which a major part of the reaction medium is propylene and the polymerization is carried in at least one CSTR or loop reactor, where the polymerization is carried out at a temperature and a pressure which are above the corresponding critical temperature and the pressure of the reaction medium and were the residence time is at least 15 minutes. The process can also have a subcritical loop polymerization before the supercritical stage polymerization or gas phase polymerization after the supercritical stage polymerization.
