Ammonium and amine salts of acids having the formula ##STR1## wherein R.sub.f is a perfluoroalkyl group; R.sub.1 is alkylene or substituted alkylene; X is --S--, --SO--, or --SO.sub.2 --; R.sub.2 is hydrogen, alkyl, aryl, substituted aryl, --B--COOH or a --B--COO anion; B is a covalent bond, arylene or alkylene; Z is the ammonium or amine cation; p is the anionic charge, q is the cationic charge; and p.sub.1 and q.sub.1 are the balanced mole equivalents respectively, are provided. These salts applied in the form of aqueous dispersions or emulsions, are useful in rendering cellulosic and natural and synthetic polyamide materials oil and water repellent.
提供以下公式的酸的铵盐和胺盐:##STR1##其中R.sub.f是全氟烷基;R.sub.1是烷基或取代烷基;X是--S--,--SO--或--SO.sub.2--;R.sub.2是氢,烷基,芳基,取代芳基,--B--COOH或--B--COO阴离子;B是共价键,芳基或烷基;Z是铵离子或胺阳离子;p是阴离子电荷,q是阳离子电荷;p.sub.1和q.sub.1分别是平衡的摩尔当量。这些盐以水分散液或乳液的形式应用,可用于使纤维素和天然及合成聚酰胺材料具有油和水的防水性。
