    Abstract: The copolymers have mol. wt. of 1000-10000 and a gel point of 15 degrees C, and are made by polymerising at 100-160 degrees C, at least temporarily under reduced pressure and at reflux, of a mixture of (a) 55-97 wt% acrylic acid esters of 3-12C non-tertiary alkanols; (b) 3-25 wt% of >=1 (meth)acrylic acid ester contg. a OH grp.; and (c) 0-20 wt% other monoethylenically unsatd. monomers, in the presence of free radical catalysts and opt. polymerisation regulators and solvents. The resulting polymers are completely compatible with polyetherols (made e.g. by reacting epoxypropane or epoxyethane with polyols) and may be used in plasticisers, e.g. in polyacrylates and polyurethanes, and in coatings, primers, adhesives and sealants.
