Abstract:
A resin obtainable from a compound of the formula 1 in whichX is â€”OH, Y is in the ortho, meta or para position relative to X, and is a radical of the formula 4 â€ƒin which R5 is C1-C30-alkyl, C2-C30-alkenyl, C6-C18-aryl, or C7-C30-alkylaryl where, by performing the steps A) or B) with formula 1 and the resin is obtainable from performing steps A) and B), which can be carried out in any order, ofA) reaction with an aldehyde of the formula 6 R8â€”CHOâ€ƒâ€ƒ(6) where R8 is H, C1-C30-alkyl, C2-C30-alkenyl, C6-C18-aryl or C7-C30-alkylaryl, and B) alkoxylation with a C2-C4-alkylene oxide in molar excess, such that the resulting alkoxylate has a degree of alkoxylation of from 1 to 100 alkylene oxide units per â€”OH group, and the resin has a molecular mass of from 250 to 100,000 units.
