摘要： This invention provides alkoxy acetic acid derivatives of general formula (I) wherein R is the residue of an amine, an aminoalcohol or a polyol linked to the or each -CHR'-CO- moiety via an amide or ester linkage; R' is hydrogen or a C1-4 alkyl group; R1 is an optionally substituted hydrocarbyl group of 1 to 300 carbon atoms; one of R?2 and R3¿ is independently selected from hydrogen and optionally substituted hydrocarbyl of 1 to 10 carbon atoms, the other of R?2 and R3¿ being independently selected from optionally substituted hydrocarbyl of 1 to 10 carbon atoms; m is from 3 to 200; n is from 0 to 20, provided that m/n is at least 1; and p is from 1 to 5; a process for their preparation; and their incorporation in additive concentrates and fuel compositions for internal combustion engines. Derivatives of formula (I) give rise to advantageous engine cleanliness effects.
