Conjugated diene-based polymer and rubber composition comprising the same

Abstract

This disclosure relates to a conjugated diene polymer having a low 1,2-vinyl bond content, a degree of hydrogenation of 0.12 or more and 0.30 or less, a glass transition temperature of -45°C or higher, and a solubility parameter difference of less than 0.88 from that of butadiene-based rubbers, and rubber compositions comprising the thereof. The present disclosure relates to a conjugated diene-based polymer having a low 1,2-vinyl bond content, a hydrogenation degree of 0.12 or more and 0.30 or less, a glass transition temperature of -45 ℃ or higher, and a solubility parameter difference with butadiene-based rubber of less than 0.88, and a rubber composition comprising the same.
