A polymer composition comprising water-soluble polymers and silicon oxide building blocks, which are connected by polymerization, is described. The water-soluble polymers are biocompatible and / or biodegradable polymers, such as. B. polysaccharides, proteins and / or cellulose derivatives. The polymer composition is formed by polymerizing polymerizable groups containing water-soluble polymers with polymerizable groups containing alkoxysilanes, their hydrolyzates or the silicon oxide sols formed from them, and as a carrier material, e.g. B. as a matrix or coating for biologically active agents, preferably active pharmaceutical ingredients that are to be released in a controlled manner. |
