MODIFIED CONJUGATED DIENE RUBBER, METHOD FOR PRODUCING SAME, AND RUBBER COMPOSITION |
摘要 |
A method for producing a conjugated diene rubber which can be used as a starting material for a crosslinked rubber that is used in applications such as a tire tread and is capable of improving the low fuel consumption performance is provided. A method for producing a modified conjugated diene rubber, comprising (A) a step of obtaining a modified conjugated diene rubber by reacting a conjugated diene compound or a conjugated diene polymer which is obtained by polymerizing a conjugated diene compound and an aromatic vinyl compound and has an alkali metal or alkaline-earth metal active end, with a first hydrocarbyloxysilane compound having the following functional groups (a) and (b):
Functional group (a): an alkyl polyether group
Functional group (b): a group convertible into an onium. |
