MULTI-COMPONENT COPOLYMER, RUBBER COMPOSITION, RESIN COMPOSITION, TIRE, AND RESIN PRODUCT
Document Type and Number:
WIPO Patent Application WO/2020/066480
Kind Code:
A1
Abstract:
Provided are: a multi-component copolymer which can bring about high durability and comprises conjugated-diene units, unconjugated-olefin units, and aromatic vinyl units, the amount of vinyl bonds in the conjugated-diene units being 3% or larger; a rubber composition and a resin composition each containing the multi-component copolymer; a tire obtained using the rubber composition; and a resin product obtained using the resin composition.
