Title:
VULCANIZED RUBBER COMPOSITION AND TIRE
Document Type and Number:
WIPO Patent Application WO/2022/270122
Kind Code:
A1
Abstract:
This invention addresses the problem of providing a vulcanized rubber composition excellent in performance on ice without lowering performance such as wear resistance. To solve this problem, the present invention provides a vulcanized rubber composition obtained by vulcanizing a rubber composition containing a rubber component and a resin component, the vulcanized rubber composition characterized in that the rubber component contains an isoprene skeleton rubber and at least one selected from styrene-butadiene rubber and butadiene rubber, and the resin component has a softening point higher than 110°C, a polystyrene equivalent weight-average molecular weight of 200–1600 g/mol, and a plurality of voids.
