    • Surfactants of formula (I) wherein each R is independently hydrogen or a C1 to C4 alkyl group; A is independently hydrogen or —C(O)—O—B; Ro is a linear, branched or cyclic aliphatic group, or combination thereof, having from about 2 to about 100 carbon atoms, interrupted or substituted by 1 to about 50 hydrophilic groups, said hydrophilic groups selected from the group consisting of hydroxyl, amino, ether and mixtures thereof; wherein specific ratios of and bonding of hydrophilic groups to carbon atoms is required; each B is independently of specific formulae containing perfluoroalkyl and —S(CH2)t—, and m, d, n, and t are 0 or integers with specific limitations.
    • 式(I)的表面活性剂,其中每个R独立地为氢或C 1至C 4烷基; A独立地是氢或-C(O)-O-B; R 2是具有约2至约100个碳原子的直链,支链或环状脂族基团或其组合,被1至约50个亲水基团间隔或取代,所述亲水基团选自 由羟基,氨基,醚及其混合物组成的组; 其中需要亲水基团与碳原子的特定比例和键合; 每个B独立于含有全氟烷基和-S(CH 2)n - 的具体式,m,d,n和t为0或具有特定限制的整数。
