  The present invention relates to a process for a chain extension of radicals bonded to silicon via carbon in silanes or siloxanes while maintaining or increasing the number of functional groups on the respective Si—C-bonded radicals, wherein a silane or siloxane with a radical bonded to a silicon atom by a carbon atom, which bears at least two functional groups, wherein a first group of the functional groups is an unsaturated, organically polymerizable group and a second group of the functional groups is selected from among (a) additional unsaturated, organically polymerizable groups, (b) COOR 8 or —(O) b P(O)(R 5 ) 2 and (c) —OH, with R 8 equal to R 4 or M 1/x x+ wherein M x+ is a hydrogen or an x-fold positively charged metal cation, and b=0 or 1, is converted in a first reaction with a compound of a formula (I) X—W—(Z) a (I) wherein X is SH, NH 2 or NHR 4 , Z is OH, the carboxylic acid radical —COOH or a salt or an ester of this radical or a silyl radical, W is a substituted or non-substituted hydrocarbon, the chain of which can be interrupted by —S—, —O—, —NH—, —NR 4 —, —C(O)O—, —NHC(O)—, —C(O)NH—, —NHC(O)O—, —C(O)NHC(O)—, —NHC(O)NH—, —S(O)—, —C(S)O—, —C(S)NH—, —NHC(S)—, —NHC(S)O—, and a is 1, 2, 3, 4 or a greater whole number, wherein R 4 is a non-substituted or substituted hydrocarbon radical, R 5 is a non-substituted or substituted hydrocarbon radical or OR 6 , R 6 is hydrogen or a non-substituted or substituted hydrocarbon radical to such an extent that the radical X connects to the first functional group. Furthermore, the invention relates to multiple processes, which, based on the aforementioned first reaction, comprise additional process steps and either lead to compounds/silicic acid polycondensates with reactive groups Q, wherein Q is OH, NR 7 2 , NR 7 3 + , CO 2 H, SO 3 H, PO(OH) 2 PO(OR 4 ) 2 or a salt of the aforementioned acids, wherein R 4 has the meaning specified above for formula (I), and R 7 either has the same meaning as R 4 or two radicals R 7 together can represent a potentially substituted, potentially unsaturated alkylene group, or to compounds/silicic acid polycondensates, in which unsaturated, organically polymerizable groups are located farther out, wherein the Si—C-bonded radicals can potentially have a dendrimer-like structure. Products of the process pursuant to the invention and organic polymers produced as a result are likewise encompassed by the invention.
