Claims
- 1. A process for vulcanizing a saturated elastomer having active halogen-containing cure sites selected from the group consisting of copolymers of ethylene and a vinyl ester of from 3 to 6 carbon atoms and having active halogen-containing cure sites incorporated therein by polymerizing a vinyl monomer containing said halogen-containing group or by chemically modifying the copolymer by reacting a portion of the ester groups with a halogen-containing reagent and poly(ethyl acrylate) or a copolymer or ethyl acrylate with n-butyl acrylate and having active halogen-containing cure sites incorporated therein by copolymerizing or terpolymerizing a vinyl monomer containing said halogen-containing group which comprises combining said elastomer with 0.05 to 2.5 sulfur and 0.05 to 7 phr quaternary ammonium salt corresponding to the formula ##STR3## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are hydrocarbon radicals having from 1 to 18 carbon atoms and X.sup.- is Cl.sup.-, Br.sup.-, I.sup.-, HSO.sub.4.sup.-, or H.sub.2 PO.sub.4 and hating said mixture at a temperature from about 100.degree. C. to about 250.degree. C. to effect vulcanization.
- 2. The process of claim 1 wherein the vulcanization is carried out at a temperature from 130.degree. C. to 200.degree. C.
- 3. The process of claim 2 wherein the elastomer contains .alpha.-chloroacetoxy groups and 0.3 to 1.5 weight percent chlorine selected from the group consisting of ethylene-vinyl acetate copolymers and ethyl acrylate homopolymers and copolymers.
- 4. The process of claim 3 wherein the saturated elastomer contains 25 to 100 phr filler/reinforcing agent.
- 5. The process of claim 4 wherein the saturated elastomer contains 2 to 6 phr quaternary ammonium salt, 0.2 to 1.3 phr sulfur, 0.25 to 1.5 phr antioxidant, 1 to 3 phr C.sub.12-18 fatty acid or mixture of C.sub.12-18 fatty acids, and 30 to 60 phr carbon black.
