Title:
METHOD FOR PRODUCING MODIFIED POLYMER, MODIFIED POLYMER, RUBBER COMPOSITION AND PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2017/033693
Kind Code:
A1
Abstract:
The objective of the present invention is to provide: a method for producing a modified polymer which is capable of reducing the heat generation of a tire; a modified polymer which is obtained by this production method; a rubber composition which contains this modified polymer; and a pneumatic tire which uses this rubber composition. A method for producing a modified polymer according to the present invention is a production method of a modified polymer which is obtained by modifying a conjugated diene polymer (A) with a nitrone compound (B) having a carboxy group. In this method for producing a modified polymer, the nitrone compound (B) is in the form of particles that have an average length in the long side direction of 50 μm or less.
