Abstract
Improved process for preparing a cross-linked epichlorohydrin elastomer composition by heating an epichlorohydrin elastomer in the presence of a compound selected from the group consisting of the quinones and derivatives thereof of the following formula ##SPC1## Wherein R.sub.1, R.sub.2 and R.sub.3, which may be the same or different, are each a member selected from the class consisting of hydrogen and the hydrocarbon groups, and R.sub.1 and R.sub.2 taken together, may form a benzene ring.
