Claim 0:
1. A polymer, comprising: monomeric units of general formula (I), 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, unsubstituted or substituted,
R2=independently from each other selected from the group consisting of hydroxyl substituted hydrocarbyl radicals,
R3 and R4 independently from each other selected from the group consisting of H and methyl, and
with the monomeric units of general formula (I) making up at least 90 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 6 to 32, 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 1:100 to 1:0.5,
wherein the polymer has a number average molecular weight Mn in the range of from 2,000 to 8,100 g/mol,
wherein the polymer has a weight average molecular weight Mw in the range of from 12,000 to 250,000 g/mol, and
wherein the Mn and Mw are selected such that the polymer has a ratio of weight average molecular weight Mw to number average molecular weight Mn in the range of from 0.1 to 3.6.
