Title:

BIFUNCTIONAL ORGANIC LITHIUM INITIATOR AND CONJUGATE DIENE SYSTEM COPOLYMER PRODUCED USING SAME

Document Type and Number:

WIPO Patent Application WO/2010/035990

Kind Code:

A2

Abstract:

The present invention relates to a polymer compound that enables the maximization of compatibility between a polymer and a reinforcement agent and a novel initiator required for the polymerization thereof, and particularly to a new polymer that has excellent miscibility with the inorganic reinforcement agents used for tire manufacturing. In addition, it relates to a copolymer prepared in such a way that said novel bifunctional initiator including an amine functional group is used for polymerization before its active terminal is subjected to denaturation with an alkoxysilane compound. If the copolymer according to the present invention is used for tires, affinity toward both carbon black used for the reinforcement agent and toward silica is enhanced at the same time, so that improvements may be obtained in the physical properties required for the tire, namely increased wet traction, reduced rotational resistance, and increased wear resistance.
