Abstract

The invention relates to compounds of the formula 1R1—O—(A—O)x—(CH2)y—R2  (1)in whichR1 is branched or straight-chain C4-C30-alkyl, C4-C30-alkenyl or C4-C30-alkylaryl,A is C2-C4-alkylene,x is an integer from 1 to 100,y is 1, 2, 3 or 4 andR2 is a radical selected from structures of the formulae 2 and 3—CO—NR3R4  (2)in which one of the radicals R3 and R4 is a hydrocarbon chain which has at least one free NH or NH2 group and the other radical is hydrogen or a hydrocarbon chain which has at least one free NH or NH2 group and R5 is hydrogen or a hydrocarbon chain which has at least one free NH or NH2 group.
