    • Fluorinated surfactants having a weight average molecular weight in a range from 1200 to 10000 grams per mole, wherein the fluorinated surfactant comprises at least one component represented by formula or a salt thereof, wherein: R is H, —CH3, or —CH2CO2H; and m is an integer having a value from 0 to 11. Z is a divalent segment consisting of copolymerized units of perfluoroalkanesulfonamidoalkyl (meth)acrylate and at least one of (meth)acrylic acid, β-carboxyethyl (meth)acrylic acid, or itaconic acid. The molar ratio of perfluoroalkanesulfonamidoalkyl to carboxylic acid groups in the fluorinated surfactant has a value from 0.5 to 3. Methods of making the fluorinated surfactants are also disclosed.
    • 重均分子量为1200〜10000克/摩尔的氟化表面活性剂,其中氟化表面活性剂包含至少一种由式或其盐表示的组分,其中:R为H,-CH 3或-CH 2 CO 2 H; m为0〜11的整数。Z为由(甲基)丙烯酸全氟烷基磺酰氨基烷基酯和(甲基)丙烯酸,(甲基)丙烯酸羧基乙酯,(甲基)丙烯酸等至少一种共聚单元构成的二价链段 衣康酸。 氟化表面活性剂中全氟烷基磺酰胺基烷基与羧酸基团的摩尔比为0.5-3。还公开了制备氟化表面活性剂的方法。
