Abstract
An elastomer containing chemically bonded metal atoms is prepared by reacting a diene elastomer such as a nitrile rubber with the reaction product of an epoxy resin and a metal containing polymer. The metal containing polymer is prepared by reacting a polycarboxylic acid and a metal complex which is a reaction product of tungsten carbonyl and/or molybdenum carbonyl with pyrrolidine.
