    • The present invention provides a process for preparing a fluorine-containing elastomer in a high productivity comparable to that of non-iodine transfer polymerization process by carrying out an iodine transfer polymerization at high pressure. The present invention also provides a fluorine-containing elastomer prepared by this process, and fluorine-containing molded articles. The process is a batch copolymerization process conducted under conditions that the reduced temperature of the critical constant is at least 0.95 and the reduced pressure of the critical constant is at least 0.80 wherein the reduced temperature and the reduced pressure are calculated using the Peng-Robinson formula from the critical temperature, the critical pressure and the composition ratio of each of the monomers in the gaseous phase in a reaction vessel, in which ethylenically unsaturated compounds containing at least one fluoroolefine are copolymerized in the presence of a compound having the formula: Rf1·Ix wherein Rf1 is a saturated or unsaturated fluorohydrocarbon or chlorofluorohydrocarbon group having 1 to 16 carbon atoms, and x is the number of bonds of Rf1 and an integer of 1 to 4.
    • 本发明提供了一种通过在高压下进行碘转移聚合制备与非碘转移聚合方法相当的高生产率的含氟弹性体的方法。 本发明还提供了通过该方法制备的含氟弹性体和含氟成型体。 该方法是在临界常数降低至少为0.95,临界常数降低至少为0.80的条件下进行的间歇共聚方法,其中降低的温度和减压是使用Peng-Robinson公式 在临界温度下,在具有下式的化合物的存在下,在反应容器中的气相中的每种单体的临界压力和组成比共聚,其中含有至少一个氟烯烃的烯键式不饱和化合物在具有下式的化合物的存在下共聚: 其中R 1是饱和或不饱和的氟代烃或其中R 1,R 2,R 3,R 4, 具有1至16个碳原子的氯氟烃基,x是R 1和...的整数1至4的整数。

    • The present invention provides a peroxide-vulcanizable fluorine-containing elastomer composition which is remarkably improved in fluidity and thereby exhibits improved processability, though conventional fluorine-containing elastomer compositions could be molded only by a molding process having a problem in its productivity, for instance, compression molding or transfer molding which has been used so far as a general molding process. The present invention further provides a molded article obtained by vulcanizing the composition. The present invention also provides a fluorine-containing elastomer composition in which a large amount of a filler can be blended. Specifically, the present invention relates to the fluorine-containing elastomer composition comprising a fluorine-containing elastomer (A) composed of a structural unit derived from vinylidene fluoride and/or a structural unit of tetrafluoroethylene and a structural unit derived from at least one other monomer, and having (a) a number average molecular weight (Mn) of 30,000 to 70,000 g/mol, and (b) an iodine content of 0.3 to 1.0% by weight and an organoperoxide vulcanizing agent (B).
    • 本发明提供了一种过氧化物可硫化的含氟弹性体组合物,其流动性显着提高,从而表现出改进的加工性能,但是常规的含氟弹性体组合物可以仅通过其生产率问题的模制方法模制, 压缩成型或传递模塑,其已经被用于一般的模塑工艺。 本发明还提供通过硫化该组合物获得的模制品。 本发明还提供了可以混合大量填料的含氟弹性体组合物。 具体地说,本发明涉及包含由偏氟乙烯衍生的结构单元和/或四氟乙烯的结构单元构成的含氟弹性体(A)和来自至少一种其它单体的结构单元的含氟弹性体组合物 (a)数均分子量(Mn)为30,000〜70,000g / mol,(b)碘含量为0.3〜1.0重量%和有机过氧化物硫化剂(B)。
