    摘要： To provide a method for producing a fluorinated polymer which does not require an emulsifier as an essential component while an aqueous medium with little environmental burden is used. A method for producing a fluorinated polymer, which comprises polymerizing at least one fluorinated polymer selected from tetrafluoroethylene, chlorotrifluoroethylene and vinylidene fluoride, in an aqueous medium in the presence of a specific polymer having at least one type of units selected from units based on a compound represented by the formula (1) and units based on a compound represented by the formula (2) to produce a fluorinated polymer (provided that when tetrafluoroethylene is polymerized, tetrafluoroethylene is polymerized so that the content of units based on tetrafluoroethylene in the fluorinated polymer becomes less than 99 mass % to all units in the fluorinated polymer):

    摘要： The present invention aims to provide a method of producing a fluoropolymer, especially a fluoropolymer essentially including a tetrafluoroethylene or chlorotrifluoroethylene unit, at a higher polymerization rate with improved efficiency, the method being capable of improving the moldability in extrusion molding and suppressing discoloration. The method of producing a fluoropolymer of the present invention includes producing a fluoropolymer by polymerizing tetrafluoroethylene or chlorotrifluoroethylene in the presence of a peroxydicarbonate. The peroxydicarbonate is represented by the formula: R—O—C(═O)—O—O—C(═O)—O—R wherein R's may be the same as or different from each other and individually represent a C4 alkyl group or alkoxy alkyl group.

    摘要： The invention relates to a polyvinylidene fluoride polymer having an ultra-high molecular weight, and unexpected physical properties. The ultra-high molecular weight polymer is clear, has a lower melting point, reduced crystallinity, excellent impact resistance, and a high elongation at the yield point. The ultra-high molecular weight polyvinylidene fluoride can be alone, or blended with other polymers, in final applications and articles.

    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 (1) represented by the formula: CH2═CR1—R2—O-(AO)p—X (in the formula, R1 is hydrogen or an alkyl group; R2 is an alkylene group having two or more carbon atoms; AO is a linear or branched oxyalkylene group having 2 to 4 carbon atoms; p is a positive integer; X is H or SO3Y wherein Y is NH4 or an alkaline metal; and AO may be the same or different and may form two or more blocks if there is more than one AO.)
