Abstract
An acrylic elastomer composition comprising (A) a halogen-containing acrylic elastomer, (B) a polyvalent carboxylic acid, (C) a quaternary onium salt and (D) a hydrotalcite can be vulcanized within a shorter vulcanization time to give a vulcanization product having distinguished normal state physical properties and compression set characteristics, even without any secondary vulcanization.
