摘要：
The present invention relates to a method for making a fluoropolymer comprising an aqueous emulsion polymerization of one or more fluorinated monomers wherein said aqueous emulsion polymerization is carried out in the presence of an oligomer that comprises one or more ionic groups, has a partially fluorinated backbone, a number average molecular weight of not more than 2000 g/mol and that has a combination of repeating units different from that of the fluoropolymer that is being produced by the polymerization of said one or more fluorinated monomers. Since the polymerization of the one or more fluorinated monomers to produce the desired fluoropolymer is carried out in the presence of the oligomer, the resulting dispersion will contain the oligomer in addition to the fluoropolymer. Thus, in a further aspect, the invention relates to an aqueous dispersion of a fluoropolymer comprising the oligomer.
摘要（中）：
本发明涉及一种制备含氟聚合物的方法，其包含一种或多种氟化单体的水乳液聚合，其中所述水性乳液聚合在包含一个或多个离子基团的低聚物存在下进行，具有部分氟化的主链， 数均分子量不大于2000g / mol，并且具有与通过所述一种或多种氟化单体的聚合产生的含氟聚合物的重复单元的重复单元的组合。 由于一种或多种氟化单体的聚合以产生所需的含氟聚合物是在低聚物存在下进行的，除了含氟聚合物之外，所得到的分散体还含有低聚物。 因此，在另一方面，本发明涉及含有低聚物的含氟聚合物的水分散体。
