Abstract: The invention relates to polytitanic acid esters having linear cross-linking structures, obtainable by reacting a titanium compound that is soluble in an alcohol, in water or in a mixture of water and alcohol and that has the composition (I) Ti(R)mXn??(I), wherein the groups R independently mean alkoxy, carboxy, or OH, X means halogen, m=0 to 4, n=0 to 4, and m+n=4, with a compound (II) that contains the following structural unit: [O?CR4—(CR5R3)p—CR1R2—O]?, wherein p is 0 or 1 and wherein (a) R1 and R2 are independently selected from among hydrogen, alkyl and alkenyl, R3 and R5 are independently selected from among hydrogen or an unsubstituted or substituted alkyl or alkenyl, R4 is OH or O(Mx+)1/x, wherein M is a metal or ammonium and x is 1 or 2, or (b) R1 and R2 together mean ?O and R3, R5 and R4 are independently selected from among hydrogen, alkyl and alkenyl, wherein the titanium compound (I) is reacted with compound (II) at a molar ratio of 1 to 0.5-1.

Abstract: The invention relates to a novel silica sol material containing at least one therapeutically active ingredient and its use for the production of bioabsorbable and biodegradable silica gel materials with improved properties. The materials, such as, for example, fibers, fleeces, powder, monolith and/or coating are employed, for example, in medical technology and/or human medicine, in particular for wound treatment.
