Title:
CONJUGATED DIENE-BASED POLYMER, MOLDED BODY, PRODUCTION METHOD FOR CONJUGATED DIENE-BASED POLYMER, RUBBER COMPOSITION, AND TIRE
Document Type and Number:
WIPO Patent Application WO/2024/034673
Kind Code:
A1
Abstract:
This conjugated diene-based polymer satisfies the following to . The Mooney viscosity measured at 100ºC is 80-170. The Mooney stress-relaxation rate (MSR) measured at 100ºC is 0.30-0.80. A downward convex extreme value is shown in a branching degree distribution curve indicating the relationship between the absolute molecular weight and the branching degree (Bn), as measured by a measurement method using GPC with a viscosity detector and a light scattering method.
