Abstract
Official abstract text for this publication.
This invention relates to a method for producing a modified conjugated diene rubber wherein the method involves: (a) a step in which a conjugated diene polymer having an alkali metal or alkaline earth metal active end and obtained by polymerizing a conjugated diene compound or by polymerizing a conjugated diene compound with an aromatic vinyl compounds is reacted with a first alkoxysilane compound which has an alkoxysilyl group having two or more alkoxy groups and has a group protected by a protecting group wherein deprotection is possible to obtain a modified conjugated-diene polymer having an alkoxysilyl group; and (b) a step in which the modified conjugated-diene polymer is reacted with a second alkoxysilane compound which has an alkoxysilyl group.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a modified conjugated diene rubber, the method comprising: (a) reacting a conjugated diene polymer comprising an alkali metal or alkaline earth metal active end with a first alkoxysilane compound comprising: an alkoxysilyl group comprising two or more alkoxy groups; and a group protected by a protecting group and capable of being deprotected, to obtain a modified conjugated-diene polymer comprising a first alkoxysilyl group; and…
