ABSTRACT:
Compositions of matter for use in oils and fuels are disclosed. The compositions arise from reaction products (C) formed by reacting substituted carboxylic acylating agents (A) with carboxylic reactants (B). The reactant (A) is usually a polyolefin substituted succinic anhydride or acid which is reacted with (B). (B) is usually a glyoxylic compound. Carboxylic reaction products (C) may further be reacted to form succinimide dispersants, esters or other derivatives. Products (C) may also be reacted with an .alpha.-.beta. unsaturated compound to form second carboxylic reaction products.
