摘要： Fatty acids commonly found in bulk elastomers such as natural rubber and certain synthetic polymers are deactivated by adding a metal oxide to the masterbatch stage where the metal oxide is selected from the group consisting of aluminum oxide, calcium oxide or mixtures thereof. Amounts range from about 0.1 phr to about 5 phr of calcium oxide, about 0.1 to about 7 phr of aluminum oxide, or about 0.5 to about 5 phr of aluminum oxide plus about 0.05 to 1 phr of calcium oxide. Deactivation of fatty acids improves tack and cure properties.

摘要： This invention is directed to treating the surfaces of rubber-reinforcing materials with a gas plasma of O.sub.2 and CF.sub.4 to activate the surfaces to make them more receptive to adhesives. Optionally the surfaces of the reinforcing materials may be exposed to a polymerizing gas plasma such as a thio-carbon to coat the surfaces of the reinforcing material with substances that promote adhesion to rubber. The treated surfaces have been shown to adhere directly to rubber when vulcanized in the normal fashion.
