  Interpolymers of 1-99 mol % vinyl fluoride and 99-1 mol % of at least one highly fluorinated monomer such as tetrafluoroethylene are disclosed. The interpolymers are characterized by the presence of ionic end groups and are prepared by polymerizing VF and fluorinated monomer in water with water-soluble free-radical initiators such as azoamidine initiators or persulfate initiators at temperatures within the range of 60 to 100° C. and reactor pressures within the range of 1 to 12 MPa (145 to 1760 psi). The invention further provides for protective self-supporting films and coatings formed from nonaqueous dispersions of the interpolymers, both for use on the surfaces of substrates including metal, plastic, ceramic, glass, concrete, fabric and wood.

  本发明公开了 1-99 摩尔%的氟化乙烯和 99-1 摩尔%的至少一种高度氟化单体（如四氟乙烯）的互聚合物。这种互聚物的特征是存在离子末端基团，其制备方法是在水中用水溶性自由基引发剂（如偶氮脒引发剂或过硫酸盐引发剂）聚合 VF 和氟化单体，温度在 60 至 100 摄氏度范围内，反应器压力在 1 至 12 兆帕（145 至 1760 磅/平方英寸）范围内。本发明进一步提供了由互聚物的非水性分散体形成的保护性自支撑薄膜和涂层，两者均可用于基材表面，包括金属、塑料、陶瓷、玻璃、混凝土、织物和木材。
