  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.

  The present invention relates to silicic acid (hetero) polycondensates comprising structural units of a following formula (1) wherein radicals, indices, and bonding symbols have the following meaning: R 1 refers to a group that is accessible to a thiol-ene polyaddition when a thiol is added and can also be polymerized by a ROMP (ring opening metathesis polymerization), R 2 is selected from (a) organically polymerizable groups that are available to a thiol-ene polyaddition when a thiol is added, but not to a ROMP, (b) —COOR 8 with R 8 equal to R 4 or M 1/x x+ , (c) —OH or COOH, and (d) —(O) b P(O)(R 5 ) 2 , wherein b is equal to 0 or 1, —SO 3 M 1/x x+ , NR 7 2 or NR 7+ 3 , wherein M x+ is an x-fold positively charged metal cation, R 4 is a non-substituted or substituted hydrocarbon radical, the radicals R 5 independently represent a non-substituted or substituted hydrocarbon radical or OR 6 and R 6 is hydrogen or a non-substituted or substituted hydrocarbon radical, R 7 has either the same meaning as R 4 or two radicals R 7 together represent a double-bonded, substituted or non-substituted, saturated or unsaturated hydrocarbon group, R 3 represents a radical bonded to a silicon atom of said formula (1) by a carbon atom, to which the radical R 1 is bonded o-fold and the radical R 2 is bonded n-fold and which is equivalent or has different meanings in the same condensate, each of the indices, n and o represents 0, 1, 2 or greater than 2 with the stipulation that n+o represents at least 2, at least one of the three bonds of a Si atom not further identified represents an oxygen bridge to an additional silicon atom or potentially to another metal atom, while the other two bonds either have the same meaning or instead represent an OH group, a hydrolysable group, or a radical bonded the said silicon atom via carbon, wherein each radical R 3 of said structure (1) must have at least one group R 1 or one group R 2 having the meaning specified in (a) and then, if said radicals R 3 are equal, (x) each radical has at least one group R 1 and either one group R 2 with the meaning specified in (a) or a second group R 1 (i.e. in these cases, o=2 or greater than 2), wherein, in both cases, n must be at least 1 or (xx) if, in addition, n is equal to 0, at least two groups R 1 have a different meaning, and then, if the radicals R 3 are different, a first part of the radicals has at least one group R 1 and one of the following two conditions must be complied with: (x) an additional part of the radicals has at least one group R 2 with the meaning specified in (a) or (d), and (xx) two different radicals R 3 have at least one group R 1 (i.e. o=1 or greater than 1). The invention also relates to the production of condensates as well as their possible uses.
