Abstract
Scorch (the premature cross-linking of an elastomer) is a problem that is often encountered in carboxylated rubbers in the presence of metal oxides which are used as cross-linking agents. Oligomerized fatty acids can be distributed throughout a carboxylated rubber to improve the scorch resistance of the resulting carboxylated rubber composition without significantly affecting the cure rate of that rubber composition. This invention discloses a process for improving the scorch resistance of a carboxylated rubber composition comprising distributing throughout a carboxylated rubber at least one oligomerized fatty acid to improve the scorch safety of said rubber composition without significantly affecting the cure rate of said rubber composition.
