Document Type and Number:
Japanese Patent JP7466430
Kind Code:
B2
Abstract:
Provided are an elastomer composition and a tire capable of changing tire performance in response to changes in temperature. The present invention relates to an elastomer composition containing a styrene-based elastomer, and a temperature-responsive resin that changes its hydrophilicity with changes in temperature, the elastomer composition satisfying the following relationship at two given temperatures differing by at least 10°C: (Contact angle at lower temperature)/(Contact angle at higher temperature) ≤ 0.90, the lower temperature being lower than 25°C.
