ABSTRACT:
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.
