Wall Character: Experimental; basic research Description: Organic polymers are needed that are resistant to tempera-tures of 500C or more. In order to prepare such materials, information is needed on the relationship between chemical structure and thermal stability. The purpose of this project is to obtain this basic information with respect to the fluorocarbons which are among the most stable of the organic materials. Present status: Active Results: The compound 2, 3, 4, 5, 6-pentafluorostyrene was found to have an unexpectedly high thermal stability and resistance to oxidation, being much superior to ordinary polystyrene.
