ABSTRACT:
A polyalkylene succinimide composition prepared by reacting a mixture of an acid derivative, a polycarboxylic acid derivative; and a polyamine under reactive conditions. The acid derivative can be an alkenyl or alkylsuccinic acid derivative, a copolymer of a first unsaturated acidic reagent and a 1,1-disubstituted olefin, or mixtures of the alkenyl or alkylsuccinic acid derivative and the copolymer. The total reaction mixture contains from 4 to 40 wt. % of the polycarboxylic acid derivative, and contains from 0.1 to 1.5 equivalents of polyamine per equivalent of acidic groups of the acid derivative plus the acidic groups of the polycarboxylic acid derivative.
