A process for the preparation of polyhydroxyl compounds by free-radical-initiated polymerisation of a) a mixture of olefinically unsaturated monomers which contain at least 1% by weight of alcoholic hydroxyl-containing monomers, b) cyclic compounds which can react in the sense of a ring-opening polymerisation reaction in the presence of alcoholic hydroxyl-containing compounds as initiator, in the presence of c) polyhydric alcohols, the polyhydroxyl compounds obtained by this process, and their use, optionally in a form which has been at least partially transesterified by means of alkyl acetoacetates, as a binder component in one- or two-component paints (surface coatings, lacquers, varnishes, enamels). |
