Document Type and Number:

WIPO Patent Application WO/2021/246509

Kind Code:

A1

Abstract:

Provided is an acrylic rubber having excellent rollability, strength characteristics, and compression set resistance characteristics. The acrylic rubber according to the present invention has an ion-reactive group, and has a number-average molecular weight (Mn) in the range of 100,000-500,000, and a ratio (Mw/Mn) of a weight-average molecular weight (Mw) to a number-average molecular weight (Mn) in the range of 3.7-6.5, as determined from absolute molecular weights and absolute molecular weight distributions as measured by GPC-MALS.
