Abstract
Rubber compositions and articles such as tires having improved metal adhesion and metal adhesion retention to brass and brass-plated metallic reinforcement. The improvement comprises admixing from about 0.2 to about 6.0 parts per hundred rubber (phr) of a compound selected from the group consisting of 3-amino-2-carboxy-4-chlorobenzophenone, 3-hydroxy-2-methyldiphenylamine and 5-amino-2-methyl-N-phenylbenzensulfonamide and mixtures thereof with a vulcanizable rubber composition prior to embedding the metallic reinforcement therein and curing. A method for improving the metal adhesion and metal adhesion retention between a vulcanizable rubber and brass or brass-plated metallic reinforcement includes the step of dispersing from about 0.2 to about 6.0 phr of a compound selected from the group consisting of 3-amino-2-carboxy-4-chlorobenzophenone, 3-hydroxy-2-methyldiphenylamine and 5-amino-2-methyl-N-phenylbenzenesulfonamide and mixtures thereof in a vulcanizable rubber composition prior to curing.
