METHOD FOR PREPARING CONJUGATED DIENE-BASED POLYMER BY CONTINUOUS POLYMERIZATION

Title:

METHOD FOR PREPARING CONJUGATED DIENE-BASED POLYMER BY CONTINUOUS POLYMERIZATION

Document Type and Number:

WIPO Patent Application WO/2019/083092

Kind Code:

A1

Abstract:

The present invention relates to a method for preparing a conjugated diene-based polymer by continuous polymerization using two or more reactors, and relates to a method for preparing a conjugated diene-based polymer, the method controlling the polymerization reaction in each reactor by regulating the ratio of polymers and monomers in each reactor and the retention time in a second reactor, thereby providing a conjugated diene-based polymer having an excellent cis-1,4 bond amount and linearity by resolving the deterioration of physical properties, and enabling productivity to improve by reducing the contamination of the reactors.
