Abstract
Scorch (the premature cross-linking of an elastomer) is a problem that is often encountered in carboxylated rubbers. Salts of certain succinic acid derivatives can be used to greatly improve the scorch resistance of carboxylated rubbers. These salts can be distributed throughout a carboxylated rubber using any procedure that will result in a thorough mixing to form a rubber composition with improved scorch resistance.
