Abstract
A process for the production of polyhalocarbon oxides not requiring the use of light is disclosed. This process involves introducing into a reaction zone perhaloolefin and ozone. The polymers obtained are substantially free of oxidizing linkages. The polyhalocarbon oxides and hydrolyzed products obtained therefrom are useful as intermediates for stabilized materials useful, for instance, as heat transfer media and lubricants, and for cured materials useful, for instance, in sealant systems and adhesive systems.
