Novel fluorodioxoles which may have Cl or F substituents in the 4 or 5 positions and have two F or CF.sub.3 substituents in the 2 position are useful monomers for the preparation of homopolymers and copolymers with tetrafluoroethylene and terpolymers with tetrafluoroethylene and vinylidene fluoride. The homopolymers are suitable for glazing materials, while copolymers are useful, among others, for corrosion-resistant seals, gaskets, and linings.
可能在4或5位置具有Cl或F取代基并在2位置具有两个F或CF.sub.3取代基的新型氟代二氧杂环烷是制备与四氟乙烯和偏氟乙烯的均聚物和共聚物以及与四氟乙烯和偏氟乙烯的三元聚合物的有用单体。该均聚物适用于玻璃材料,而共聚物则可用于耐腐蚀密封件,垫片和衬里等领域。
