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.
Composés hyperramifiés dotés d'un groupe central tétrafonctionnel de formule générale C [-Aq-X-]m [-Ar-X-]n [-As-X-]o [-At-X-]p dans laquelle les indices et les variables ont la signification suivante: m + n + o + p = 4, m étant un nombre entier de 1 à 3 et n, o et p étant 0 ou un nombre entier de 1à 3; q, r, s et t sont un nombre entier de 1 à 5, q étant supérieur à r, s, t; X est -O-, -S- ou -NH-; A est -CR2-, R étant -H, -F, -Cl, -Br, -CN, -NO2, un reste alkyle ou haloalkyle ou alcoxy C1-C3, ou, pour q, r, s et/ou t étant au moins 2, un reste alcanediyle et/ou oxa-alcanediyle C2-C4 qui ponte 2 à 5 atomes de carbone du reste -A-, et/ou un atome d'oxygène -O- qui ponte 3 à 5 atomes de carbone du reste -A-. La présente invention concerne également l'utilisation de ces composés en tant que constituants fonctionnels dans des mélanges de substances ou pour la fabrication de composés hyperramifiés ou dendrimères de génération supérieure.
