Title:
POLYMER COMPOSITE, RUBBER COMPOSITION, AND TIRE
Document Type and Number:
WIPO Patent Application WO/2021/246048
Kind Code:
A1
Abstract:
Provided are a polymer composite, a rubber composition, and a tire with which it is possible to reversibly change tire performance in response to temperature changes. The present invention relates to a polymer composite comprising a conjugated diene polymer having a weight-average molecular weight, as determined by gel permeation chromatography, of 100,000 or higher, the polymer composite having a temperature dependency of contact angle with water which, at two temperatures differing by 10°C or more, reversibly satisfies the following relationship (II). Relationship (II): Temperature dependency of contact angle = Lower-temperature contact angle / Higher-temperature contact angle × 100 ≤ 90
