Novel fluorodioxoles which may have Cl or F substituents in the 4 or 5 positions and have two F or CF3 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.
在 4 位或 5 位可能有 Cl 或 F 取代基、在 2 位有两个 F 或 CF3 取代基的新型二氧氟环 己烷是制备均聚物、与四氟乙烯的共聚物以及与四氟乙烯和偏氟乙烯的三元共聚物 的有用单体。均聚物适用于玻璃材料,而共聚物则适用于耐腐蚀密封件、垫圈和衬里等。
