ABSTRACT:
The new polyester polyols, which have an acid value below 10, a hydroxyl value of 50 to 200, a hydroxyl functionality above 2 and a number average molecular weight M.sub.n of 800 to 5,000 and which are liquid at 23.degree. C. or are homogeneously soluble in di-2-ethylhexyl phthalate in a concentration of at least 70% by weight, the viscosity of the 70% solution being from 1 to 35 Pa.s, are used as anchoring agents for polymer systems and as polymeric plasticizers.
