Abstract

The present invention relates to novel modified polyaminoamides which are useful as dispersing agents for particulate inorganic solids, especially for inorganic pigments such as clay minerals. The new polyamides are also useful as graying inhibiting additives and detergency boosting additives in washing composition for laundry. In the modified polyaminoamide according to the invention at least a part of the amino nitrogens of the polymer carry both a hydrocarbon radical R which is selected from C1-C6-alkyl, C6-C16-aryl-C1-C4-alkyl and a group AIk-O-A, wherein A is hydrogen or an acidic group selected from B1—PO(OH)2, B1—S(O)2OH and B2—COOH which may be present in the acidic or anionic form, wherein B1 is a single bond or C1-C6-alkanediyl, and B2 is C1-C6-alkanediyl and Alk is C2-C6-alkane-1,2-diyl, and a moiety of the formula (I) —(CH2—CR1R2—O—)pA ,wherein A is as defined above R1 is independently selected from hydrogen, C1-C12-alkyl, C2-C8-alkenyl, C6-C16-aryl or C6-C16-aryl-C1-C4-alkyl, R2 is independently selected from hydrogen or methyl and p is an integer provided that p has a number average of at least 10.
