Document Type and Number:

WIPO Patent Application WO/2020/235662

Kind Code:

A1

Abstract:

The present invention provides: a resin composition which exhibits high vibration damping performance even at relatively high temperatures, while having good moldability and excellent impact resistance; and the like.
