    • A no-post-cure method of curing polyacrylates having dual cure sites is accomplished with a two-part curing system or a combined one-part curing system. The two-part curing system consists of one or more metallic acid salts and an ammonium and/or phosphonium quaternary salt. The one-part curing system consists of an ammonium or phosphonium quaternary acid salt. The polyacrylate rubber must have both a halogen and a carboxyl cure site. The method consists of blending the curative with the polyacrylate rubber and heating the resultant composition until the composition cures. Because the mixed composition is shelf stable, it is not necessary to immediately heat the composition to cure it. The method may optionally include the step of storing the mixed composition until it is desired to cure it.
    • 具有双重固化位点的固化聚丙烯酸酯的无后固化方法通过两部分固化体系或组合的一部分固化体系实现。 两部分固化体系由一种或多种金属酸盐和铵和/或鏻季盐组成。 一部分固化体系由铵或鏻季铵盐组成。 聚丙烯酸酯橡胶必须同时具有卤素和羧基固化部位。 该方法包括将固化剂与聚丙烯酸酯橡胶混合并加热所得组合物直到组合物固化。 由于混合组合物是稳定的,所以不需要立即加热组合物来固化。 该方法可以任选地包括存储混合组合物的步骤,直到需要使其固化。
