A curing system for carboxylic rubbers contains as an essential part a polyvalent metal at least part of which is present as a peroxide. Preferred metals are calcium, magnesium, zinc and mixtures thereof. The balance of the metal is preferably present as the oxide or hydroxide of the same or a different polyvalent metal. The carboxylic rubbers may be copolymers of conjugated dienes and ethylenically unsaturated carboxylic acids, or copolymers of acrylic or methacrylic esters with ethylenically unsaturated acids. |
