    摘要: An object of the present invention is to provide a method for producing a fluoropolymer which produces a large number of particles with a small particle size using a specific non-fluorous compound having surfactant ability. The method for producing a fluoropolymer includes aqueous dispersion polymerization of a monomer including at least one fluoroolefin in the presence of a compound represented by the formula: CH2═CHCH2—O—(C═O)CHXCH2COO(CH2)nCH3 (in the formula, X is H or SO3Y wherein Y is NH4 or an alkaline metal; and n is an integer of 0 to 19.)

    摘要: 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.

    摘要: Process for the production of PCTFE homopolymer and/or copolymer resins by the use of an aqueous suspension system incorporating a redox initiator system which comprises t-butyl hydroperoxide and sodium metabisulfite to initiate the polymerization or copolymerization process. The process parameters may be controlled to provide a PCTFE homopolymer or copolymer resin having a desired target range of molecular weights. The process provides stable PCTFE polymer suspensions which exhibit a low tendency to coagulate and further exhibit good wettability of the homopolymer and copolymer particles, notably in the absence of soaps.

[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.
