    • A method of producing a fluoropolymer by which a melt-processable fluoropolymer (A) having a specific unstable terminal group or groups (P) is subjected to melt-kneading in a kneader having a stabilization treatment zone to thereby produce a fluoro-polymer (B) resulting from conversion of the specific unstable terminal group or groups (P) to —CF2H. The specific unstable terminal group or groups (P) include alkoxycarbonyl groups, fluoroalkoxycarbonyl groups and/or carboxyl group quaternary nitrogen compound salts, the melt-kneading is carried out in the absence or presence of an alkali metal element or alkaline earth metal element, the content of the alkali metal element or alkaline earth metal element is not greater than 2 ppm of the composition under melt-kneading, and the melt-kneading in the stabilization treatment zone is carried out in the presence of water. A fluoro-polymerised material is also disclosed.
    • 在具有稳定化处理区域的捏合机中对具有特定不稳定末端基团(P)的可熔融加工的含氟聚合物(A)进行熔融混炼的含氟聚合物的制造方法,由此制造氟聚合物 )由特定的不稳定末端基团(P)转化为-CF 2 H而得到。 特定的不稳定末端基(P)包括烷氧基羰基,氟代烷氧基羰基和/或羧基季氮化合物盐,在不存在或不存在碱金属元素或碱土金属元素的情况下进行熔融混炼, 在熔融捏合下,碱金属元素或碱土金属元素的含量不超过组合物的2ppm,稳定化处理区的熔融捏合在水的存在下进行。 还公开了氟聚合材料。

    • 723,445. Polymerization; perhalopolymers. KELLOGG CO., M. W. April 18, 1952 [May 11, 1951], No. 9792/52. Drawings to Specification. Class 2 (5). [Also in Group IV (b)] Liquid or solid perhalo-polymers are made by polymerizing, e.g. in a solvent or diluent, a perhalo-olefin alone or with another perhalo-olefin or with another halogen-containing organic monomer in the presence of a completely or partially chlorinated and/or fluorinated aliphatic acyl peroxide having at least 6 carbon atoms per molecule as catalyst, and optionally a chain-terminating agent which may be the solvent. The concentration of the catalyst is preferably maintained during the polymerization between 0.01 and 0.5 per cent of the olefin for solid polymers and between 0.5 to 10 per cent for liquid polymers. Perhalo-olefins and monomers mentioned are trifluorochloroethylene, tetrafluorethylene, perfluorobutadiene, difluorodichloroethylene, perfluoropropene, perfluoromonochloropropene, perfluorobutene, perfluoromonochlorobutene, diphenyldifluoroethylene, vinylidene fluoride, vinyl fluoride, vinyl chloride, vinylidene chloride, and perfluorostyrene. The catalyst may be trifluorodichloropropionyl, trichlorodifluoropropionyl, tetrafluorochloropropionyl, tetrachlorofluoropropionyl, perfluoropropionyl, perchloropropionyl, tetrachloropropionyl, tetrafluoropropionyl, fluoropropionyl, pentafluorodichlorobutyryl, pentachlorodifluoro-, butyryl, tetrafluorotrichlorobutyryl, tetrachlorotrifluorobutyryl, perfluorobutyryl, perchlorobutyryl, tetrachlorobutyryl, tetrafluorobutyryl, fluorobutyryl, septafluorodichlorovaleryl, pentafluorotetrachlorovaleryl, pentachlorotetrafluorovaleryl, perfluorovaleryl, perchlorovaleryl, tetrachlorovaleryl, tetrafluorovaleryl, or fluorovaleryl peroxide. Solvents and diluents mentioned are water, chloroform, hydrocarbon oils, carbon tetrachloride, bromotrichloromethane, trichlorotrifluoroethane, tetrachloroethane, and trichlorofluoromethane. Specification 694,164 is referred to.
