    • Provided are methods for using compositions of matter which exist in a powdered, free-flowing form to which water is added preferable just prior to the time of use, to yield flowable liquid compositions which are spreadable, dispersible or sprayable onto various substrates. In some embodiments the free-flowing compositions contain water-soluble styrene/acrylic acid copolymers, and can surprisingly comprise relatively large amounts of water on the order of about 20% or more, while remaining in the form of a free-flowing powder prior to their combination with additional water to yield the spreadable, dispersible or sprayable liquid compositions. By the present disclosure, shelf life concerns are eliminated, as the compositions provided have an essentially indefinite shelf life, and transportation and handling ease are greatly increased over prior art compositions due to less weight by the absence of large relative quantities of water present in prior art compositions.
    • 提供了使用以粉末状,自由流动的形式存在的物质组合物的方法,其优选在使用之前优选加入水,得到可扩散,可分散或可喷涂到各种基材上的可流动的液体组合物。 在一些实施方案中,自由流动的组合物含有水溶性苯乙烯/丙烯酸共聚物,并且可以令人惊讶地包含约20%或更多量级的较大量的水,同时保持为自由流动的粉末的形式,然后 它们与额外的水的组合以产生可铺展的,可分散的或可喷雾的液体组合物。 根据本公开,由于所提供的组合物具有基本上无限期的保存期限,所以消除了保质期问题,并且与现有技术组合物相比,运输和处理容易性由于较少的重量而由于较少的重量而不存在先前存在的大量相对量的水 艺术作品。

    • A fluorinated copolymer composition comprises ethylene/tetrafluoroethylene-containing copolymer and copper oxide. The ethylene/tetrafluoroethylene-containing copolymer comprises repeating units (A) based on ethylene, repeating units (B) based on tetrafluoroethylene and repeating units (C) based on another monomer, in a molar ratio of the repeating units (A) to the repeating units (B) of from 38/62 to 44/56, and in an amount of the repeating units (C) of from 0.1 to 2.6 mol % in all the repeating units of the ethylene/tetrafluoroethylene-containing copolymer. The content of the copper oxide is from 0.2 to 10 ppm based on the total weight of ethylene/tetrafluoroethylene-containing copolymer. The copper oxide has a BET surface area of from 5 to 30 m2/g. The volume flow rate of the fluorinated copolymer composition at 297° C. is from 15 to 150 g/10 min.
    • 含氟共聚物组合物包含含乙烯/四氟乙烯的共聚物和氧化铜。 含乙烯/四氟乙烯的共聚物包含基于乙烯的重复单元(A),基于四氟乙烯的重复单元(B)和基于另一单体的重复单元(C),重复单元(A)与重复单元 单位(B)为38/62〜44/56,在乙烯/四氟乙烯共聚物的全部重复单元中的重复单元(C)为0.1〜2.6摩尔%。 氧化铜的含量相对于含乙烯/四氟乙烯的共聚物的总重量为0.2〜10ppm。 氧化铜的BET表面积为5〜30m 2 / g。 含氟共聚物组合物在297℃下的体积流速为15-150g / 10min。
