Title:
MODIFIED CONJUGATED DIENE POLYMER, METHOD FOR PRODUCING THE SAME, MODIFIED CONJUGATED DIENE POLYMER COMPOSITION, AND TIRE
Document Type and Number:
WIPO Patent Application WO/2010/044252
Kind Code:
A1
Abstract:
Provided is a modified conjugated diene polymer having one or more nitrogen atoms and one or more silyl groups substituted by alkoxy groups at the terminals of the conjugated diene polymer. The modified conjugated diene polymer is obtained by using a polyfunctional anionic polymerization initiator wherein the molar ratio of polyvinyl aromatic compound and organic lithium compound (polyvinyl aromatic compound/organic lithium compound) has been adjusted to within a range of 0.05 to 1.0 and reacting a compound having one or more nitrogen atoms and two or more silyl groups substituted by alkoxy groups with the polymerization-active terminals of a conjugated diene polymer obtained by polymerization of a conjugated diene compound or copolymerization of a conjugated diene compound and an aromatic vinyl compound.
