Abstract

This invention relates to a method for preparing heat-stablized elastomers, particularly silicone elastomers. Metal oxides, especially those of cerium, are effective heat stabilizers for the silicone elastomers. Such elastomers are used as fuser roll coatings in copying machines. The effectiveness of such metal oxides to heat stabilize the elastomers increases as their particle size decreases. Ac-cordingly, it is desired to obtain extremely fine metals and metal oxides in the elastomers.
