Zusammenfassung:The invention relates to polyesterols obtainable by reaction of b1) from 10 to 70 mol% of at least one compound selected from the group consisting of terephthalic acid, dimethyl terephthalate, polyethylene terephthalate, phthalic anhydride, phthalic acid and isophthalic acid, b2) from 0.8 to 4.5 mol% of a fatty acid triglyceride, b3) from 10 to 70 mol% of a diol selected from the group consisting of ethylene glycol, diethylene glycol and polyethylene glycols, b4) from 5 to 50 mol% of a polyether polyol having a functionality of greater than 2, wherein at least 200 mmol of component b4) are used per kg of the polyesterol, where the sum of the components b1) to b4) adds up to 100 mol%.
