Title:
MULTI-COMPONENT COPOLYMER, RUBBER COMPOSITION, RESIN COMPOSITION, TIRE, AND RESIN PRODUCT
Document Type and Number:
WIPO Patent Application WO/2020/235285
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a copolymer having reduced heat generation in low-strain areas. The solution for said problem being a multi-component copolymer comprising a non-conjugated olefin unit, a conjugated diene unit, and an aromatic vinyl unit, the multi-component copolymer characterized in that the ratio [(C100-120/C0-100) × 100] of crystallinity (C100-120) derived from the non-conjugated olefin unit at 100-120°C relative to crystallinity (C0-100) derived from the non-conjugated olefin unit at 0-100°C, as measured by a differential scanning calorimeter (DSC), is 23% or less.
