Title:
METHOD FOR PREPARING OLEFIN-BASED POLYMER BY GAS-PHASE POLYMERIZATION
Document Type and Number:
WIPO Patent Application WO/2021/118145
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing an olefin-based polymer by gas-phase polymerization. Specifically, the present invention relates to a method for preparing an olefin-based polymer by gas-phase polymerization of olefin-based monomers in a semi-batch stirring type reactor. The method for preparing an olefin-based polymer according to a specific embodiment of the present invention can prevent the polymer agglomeration caused by local overreaction while maintaining high catalytic activity during the gas-phase polymerization of olefin-based monomers, and can produce an olefin-based polymer having excellent properties.
