    • The surfactants of this invention are phenolic-formaldehyde resins that have been sulfomethylated with from 1-13 moles of sulfomethylation per 1000 grams of the starting resin and further modified by reaction with up to 20 moles, preferably 0.25 to 10 moles, per 1000 grams of starting resin of a blocking agent of the type X(CHR).sub.m (CH.sub.2).sub.n Y, wherein X is a halogen, an activated double bond, epoxy ring or halohydrin, Y is a property group such as sulfonate, phosphonate, carboxylate or hydroxyl, R is another property group such as hydrogen, hydroxyl, mercaptan or amine, and n and m are integers from 0 to 5, with n or m being at least 1, to at least partially block the phenolic hydroxyl group of the resin. The phenolic-formaldehyde resin may also be cross-linked to tailor its molecular weight and then treated with urea or ammonia, if desired.
    • 本发明的表面活性剂是酚醛甲醛树脂,其已经用每1000克原始树脂中的1-13摩尔磺甲基化磺基甲基化,并进一步通过与每1000克的最高20摩尔,优选0.25至10摩尔的反应进行修饰 X(CHR)m(CH 2)n Y型封端剂的起始树脂,其中X为卤素,活化双键,环氧环或卤代醇,Y为诸如磺酸盐,膦酸盐,羧酸盐或羟基的性质基团, R是氢,羟基,硫醇或胺等另一种性质基团,n和m为0至5的整数,n或m至少为1,以至少部分阻断树脂的酚羟基。 酚醛树脂也可以交联以调整其分子量,然后如果需要用尿素或氨处理。
