Abstract:
1. A process for making a crosslinked ethylene acrylate elastomer or a polyacrylate elastomer comprising producing an aqueous solution comprising hexamethylene diamine; blending the aqueous solution with a particulate filler under a condition that the solution deposited onto the filler to produce a dry liquid concentrate; contacting the concentrate with a copolymer to produce a mixture comprising about 0.06 to about 0.3 mole of amino function per kilogram of the copolymer; and heating the mixture wherein the copolymer is an ethylene/alkyl acrylate copolymer or a polyacrylate each containing a monoalkyl ester of a 1,4-butene-dioic acid cure-site termonomer and the filler is an inorganic material.
