MODIFIED LIQUID DIENE-BASED POLYMER, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/138535
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a diene-based polymer having excellent adsorptive properties onto silica; and a method for producing the diene-based polymer. A modified liquid diene-based polymer according to the present invention has at least one functional group A selected from the group consisting of an amino group, a hydroxyl group, a carboxyl group, an alkoxysilyl group, a monovalent group having a carbonyl group, an aldehyde group, an epoxy group, a nitro group and an alkoxysilyl group having an amino group at a terminal thereof and also has a functional group B represented by formula (1) in the main chain thereof. In formula (1), R1 represents an alkylene group having 1 to 10 carbon atoms; R2, R3 and R4 independently represent an alkoxy group having 1 to 10 carbon atoms; and * represents a binding position.
