(57) [Abstract] PROBLEM TO BE SOLVED: To provide an acrylic elastomer composition having a carboxyl group as a cross-linking site, and to improve scorch resistance, particularly at high temperatures, without lowering the vulcanization rate. I will provide a. SOLUTION: This acrylic elastomer composition comprises a carboxyl group-containing acrylic elastomer mixed with a blocked isocyanate and preferably further a guanidine, a quaternary onium salt, a tertiary amine or a tertiary phosphine as a vulcanization accelerator. . |
