Title:
COPOLYMER, RUBBER COMPOSITION, AND RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/123993
Kind Code:
A1
Abstract:
Provided is a copolymer excellent in cutting resistance and ozone resistance. This copolymer is characterized in that the copolymer has a conjugated diene unit and a non-conjugated olefin unit, the proportion of the non-conjugated olefin unit is 50 mol% or more, and the endothermic peak energy (ΔH2) within the range of 100-150°C is larger than the endothermic peak energy (ΔH1) within the range of 0°C or more to less than 100°C when measured by a differential scanning calorimeter (DSC).
