Claim 15:
16. The polymer according to claim 1, wherein
R1=independently from each other selected from the group consisting of alkyl radicals and alkenyl radicals, which both may be branched or straight chained substituted by hydroxyl-groups,
R2=independently from each other selected from the group consisting of alkyl radicals with from 1 to 10 carbon atoms,
R3and R4=H, and
with the monomeric units of general formula (I) making up for at least 95 wt.-% of the total weight of the polymer,
with at least 90 wt.-% of all R1 are selected from the group of alkyl and alkenyl radicals with from 10 to 26 carbon atoms, with the wt.-% referring to the sum of all R1 present in the polymer, and
with the weight ratio of the sum of all R2-bearing-units to the sum of all R1-bearing-units being in the range of from 1:60 to 1:0.8,
wherein the polymer has a number average molecular weight Mn in the range of from 5,000 to 8,500 g/mol.
