(1) ABSTRACT OF THE DISCLOSURE Disclosed herein is a novel composition of matter comprising a mixed polyester of the formula: Image wherein n is an average number of from about 1 to 20; and in the case of the mixed polyester derived from a trimer acid p is 1 or 2 and q is 1 or 2, the sum of p and q being 3; and in the case of the mixed ester derived from a dimer acid, both p and q are each 1; R7 is an alkyl group containing 4 to 12 carbon atoms; R8 is H or an alkyl group containing 4 to 12 carbon atoms; R9 is a straight or branched chain alkyl group containing 1 to 24 carbon atoms; and Z1 is a saturated or unsaturated hydrocarbon residue having about 34 to about 51 carbon atoms, said residue being the residue of a dimer or trimer acid or mixture thereof. Also described are detergent additive compositions suitable for addition to gasoline comprising a mixture of (1) about 20 to about 250 parts by weight of a tertiary alkyl primary amine having a branched backbone and a total of 6 to 24 carbon atoms; and (2) about 100 to about 650 parts by weight of a mixed polyester as defined above. The specification also describes a (2) multifunctional additive composition suitable for addition to gasoline comprising a mixture of (1) and (2) as defined above, together with (3) about 5 to 100 parts by weight of a surface active alkyl ammonium carboxylate salt-ethoxylated alkyl phenol ester of a trimer or dimer acid of the formula Image where n is an average number from 1 to 12.5; and wherein in the case of the salt-ester derived from a trimer acid x is 1 or 2, and y is 1 or 2, the sum of x and y being 3; and in the case of the salt-ester derived from a dimer acid, both x and y are each 1; R4 is an alkyl group containing 4 to 12 carbon atoms; R5 is H or an alkyl group containing 4 to 12 carbon atoms; R6 is an alkyl group containing 2 to 24 carbon atoms which may be straight or branched chain or an amine substituted alkyl group of 2 to 24 carbon atoms; and Z is a saturated or unsaturated hydrocarbon residue of the acid, said hydrocarbon residue having 34 to 51 carbon atoms. These compositions of matter are useful in substantially eliminating, or at least substantially reducing, deposits which would otherwise form in the intake valves and ports, and in the combustion chamber, of an internal combustion engine, and in the carburetor.
