Abstract
An acrylic elastomer composition, which comprises a carboxyl group-containing acrylic elastomer, a polyfunctional isocyanate compound or a blocked isocyanate, and at least one of a guanidine, a quaternary onium salt, a tertiary amine and a tertiary phosphine has an improved scorch resistance without lowering the normal state physical properties, heat resistance and compression set characteristics of the resulting vulcanization products, when the polyfunctional isocyanate used, or has an improved scorch resistance, particulary at high temperatures, without lowering the vulcanization speed when the blocked isocyanate is used.
