Polyoxyalkylene esters and amides of alk (en) yl succinic anhydrides of the general formulas YA • OC (HR) CC (HR) CO • A (CH O) • R; YA • OC (HR) CC (HR) CO • A (CH O) • CH A • CO (HR) CC (HR) CO • AY, where R, R, A, A, Y, R, m, n and p are defined in the description and claims, in particular when the alk (en) yl group is a C - C group, are effective surfactants. It turned out that their cloud point tends to increase with increasing chain length of the alk (en) yl group. Surfactants are effective in cleaning wool and inverting water-in-oil polyacrylamide emulsions into water. |
