Abstract
PURPOSE:To obtain the title additive which maintains low viscosity and self- flowability for a long period of time, by using a partially sulfonated PS or its salt and a polyethylenepolyamine fatty acid amide. CONSTITUTION:The subject additive contains, as essential components, (A) (i) a partially sulfonated PS of 2,000-500,000, preferably 4,000-100,000 weight- average mol.wt. or (ii) a partially sulfonated PS mixture containing a PS of 400-10,000 weight-average mol.wt. and another PS of 40,000-500,000, preferably 50,000-150,000 weight-average mol.wt., or their salts, and (B) a polyethyle nepolyamine fatty acid amide. As a component B, is cited a compound having 1-3, preferably 1 or 2 amide groups in the molecule, formed by reaction of a polyethylene-polyamine of the formula (n is 2-25, preferably 3-10 on the average) with a fatty acid of 6-25, preferably 8-19C atoms.
