Beschreibung
Zusammenfassung:	This invention provides alkoxy acetic acid derivatives of general formula I: (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 R2 and R3 is independently selected from hydrogen and optionally substituted hydrocarbyl of 1 to 10 carbon atoms, the other of R2 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.
