ABSTRACT:
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.
