Claim:
A liquid composition prepared by copolymerizing olefinically unsaturated compounds in a reaction medium of reactive diluents wherein the reactive diluents comprise polyols selected from the group consisting of (i) hyperbranched compounds containing (a) a tetrafunctional central group derived from at least one of ditrimethylolpropane, diglycerol, ditrimethylolethane and (b)a tetrafunctional central group of the general formula I C[—A q —X—] m [—A r —x —] n [—A s —X—] o [A t —X—] p (I), in which the indices and variables have the following definitions: m+n+o+p=4; where m is an integer from 1 to 3, and n, o and p are 0 or an integer from 1 to 3; q, r, s and t are an integer from 1 to 5, where q≧r, s, t, X is —O—, —S— or —NH—; A is —CR 2 —; where R is selected from the group consisting of —H, —F, —Cl, —Br, —CN, —NO 2 C 1 –C 3 alkyl or haloalkyl or C 1 –C 3 alkoxy radical or, if q, r, s and/or t are at least 2, R is selected from the group consisting of a C 2 –C 4 alkanediyl, oxaalkanediyl radical having 2 to 5 carbon atoms an oxygen atom —O— which bridges from 3 to 5 carbon atoms of the radical —A— and mixtures thereof; and (iii) polyols obtained by hydroformylating oligomers of the formula (III), R 3 R 4 C═[CH—R 2 —CH] v ═CR 5 R 6 (III), in which R 2 is —(—CH 2 —) w —, in which w is an integer from 1 to 6, or in which X is —CH 2 — or an oxygen atom; R 3 , R 4 , R 5 and R 6 independently of one another are hydrogen atoms or alkyl of from C 1 to C 10 carbon chain length; and the index v is an integer from 1 to 15.
