Abstract
Fluorinated dioxole compounds and the process of preparation are disclosed which compounds are of the formula ##EQU1## wherein R.sub.1 and R.sub.2 are both perhalogenated hydrocarbon radicals of 1 to 3 carbon atoms containing at least one fluorine atom. The compounds may be homopolymerized and copolymerized for casting into films or yielding molded articles.
Claims6
A copolymer of fluorinated dioxole of the formula ##EQU2## wherein R.sub.1 and R.sub.2 are the same or different both consisting of 1 to 3 carbon atoms which are perhalosubstituted and containing at least one fluorine atom whereby the perhalosubstitutuents are selected from the group consisting of chlorine and fluorine atoms and a comonomer selected from the class consisting of chlorotrifluoroethylene, vinylidene fluoride and hexafluoropropene.
A copolymer of perfluoro-2,2 dimethyl-1,3 dioxole and tetrafluoroethylene.
A homopolymer of perfluoro-2,2 dimethyl-1,3 dioxole.
