Title:
METHOD FOR PRODUCING ISOBUTYLENE-BASED BLOCK COPOLYMER
Document Type and Number:
Japanese Patent JP2001220401
Kind Code:
A
Abstract:
To provide a production method by which an isobutylene-based block copolymer can be stably polymerized when industrially producing the isobutylene-based block copolymer.
This method for producing the isobutylene-based block copolymer is characterized in that a stirring vessel having a stirring blade having the functions for generating the flow rising along a vessel wall to the free surface, installed therein when producing the isobutylene-based block copolymer.
