    摘要: Nonfluorinated surfactants selected from C7–C20 linear 1-alkanesulfonates, 2-alkanesulfones, and 1,2-alkanedisulfones are particularly effective for stabilizing emulsions in preparing non-elastomeric fluoropolymers containing at least 71 wt % vinylidene fluoride and having at least a 2% crystalline polyvinylidene fluoride content. Processes for making such fluoropolymers using these surfactants, particularly in combination with one or both of a nonionic polymerization initiator and the use of mechanical coagulation to isolate the product, are also provided, as are fluoropolymers made thereby.

    摘要: The present invention relates to a method for the polymerization in an aqueous medium of monomers, and especially of fluoromonomers, using non-fluorinated surfactants; and the fluoropolymers formed therefrom. Specifically, the method of the polymerization uses one or more non-fluorinated surfactants selected from the group consisting of polyvinylphosphonic acid, polyacrylic acids, polyvinyl sulfonic acid, and salts thereof. Additionally, the use of polyvinylphosphonic acid, polyacrylic acids, polyvinyl sulfonic acid as surfactants in aqueous free radical polymerization is also novel.
