DIENE POLYMER, METHOD FOR PRODUCING DIENE POLYMER, MODIFIED STYRENE-BUTADIENE RUBBER, AND DIENE POLYMER INTERMEDIATE

摘要

PROBLEM TO BE SOLVED: To provide a diene polymer functioning as a modifier that reduces a vinyl group content of a styrene-butadiene rubber, a method for producing the diene polymer, a modified styrene-butadiene rubber obtained by modifying a styrene-butadiene rubber with the diene polymer used as modifier, and a diene polymer intermediate that is an intermediate of the diene polymer.SOLUTION: A diene polymer has a vinyl group content of less than 20%, and comprises a nitrile oxide group at a terminal.SELECTED DRAWING: None
