Hyperbranched compounds having 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 meanings: m + n + o + p = 4; where m = an integer from 1 to 3 and n, o and p = 0 or an integer from 1 to 3; q, r, s and t = an integer from 1 to 5, where q > r, s, t; X = -O-, -S- or -NH-; A = -CR2-; where R = -H, -F, -Cl, -Br, -CN, -NO2, C1-C3 alkyl or C1-C3 haloalkyl or C1-C3 alkoxy radical or, if q, r, s and/or t = at least 2, a C2-C4 alkanediyl and/or C2-C4 oxaalkanediyl radical which bridges 2 to 5 carbon atoms, and/or an oxygen atom -O-, which bridges 3 to 5 carbon atoms, of the radical -A-; and also the use of these compounds as functional components in compositions of matter or for the preparation of hyperbranched or dendrimeric compounds of higher generations.
