Title:
MODIFIED DIENE-BASED POLYMER, METHOD FOR PRODUCING SAME, AND RUBBER COMPOSITION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/054631
Kind Code:
A1
Abstract:
According to the present invention, provided is a method for producing a modified diene-based polymer by melt kneading a diene-based polymer and a metal salt of an α,β-ethylenically unsaturated carboxylic acid, the method being characterized in that the metal salt of an α,β-ethylenically unsaturated carboxylic acid is at least one type of metal salt selected from a metal salt group comprising sodium acrylate, potassium acrylate, zinc acrylate, magnesium acrylate, calcium acrylate, copper acrylate and aluminum acrylate. According to the present invention, provided is a modified diene-based polymer in which the ratio of small angle X-Ray scattering intensities at q=0.04 nm-1 and q=0.7 nm-1 is 3000 or more.
