ABSTRACT:
A biocompatible material which is the product of graft-copolymerization of a water-soluble vinyl and/or an acrylate monomer with a sorption complex of polysilicic acid and collagen that has been rid of pigments, glycoproteins and proteoglycans, or a product obtained by virtue of chemical destruction, with the aid of hydrofluoric acid, of the afore-mentioned product of graft-copolymerization, containing up to 25 mass percent of polysilicic acid (in terms of SiO.sub.2), up to 12 mass percent of protein, and maximum 1 10.sup.-6 mole/g of an anion of hydrofluoric and hydrofluoric acids, methods of making the same and products produced thereby.
