Title:
METHOD FOR CONTROLLING CHAIN STRUCTURE IN COPOLYMERS
Document Type and Number:
WIPO Patent Application WO/2012/014420
Kind Code:
A1
Abstract:
Disclosed is a method for controlling the chain structure in copolymers which is capable of controlling the arrangement of monomer units in copolymers, and of making and separating random copolymers, tapered copolymers, multi-block copolymers, and block copolymers. The disclosed method for controlling the chain structure in copolymers of conjugated diene compounds and non-conjugated olefins controls the insertion of conjugated diene compounds in the presence of non-conjugated olefins, and thus controls the chain structure of the copolymers.
