NANOCOMPOSITES OF SYNTHETISED HYDROGELES PREPARED BY POLYMERISATION OF N-ISOPROPYL-ACRYLAMIDE, ACRYLAMIDE AND ACRYLACID, PROCESS FOR PREPARATION THEREOF AND THEIR USE FOR PREPARATION OF OSMOTICALLY ACTIVE HYDROGELES IN TISSUE EXPANDING EXPANDERS

摘要

The invention relates to nanocomposites comprising of (i) hydrogels synthetized by copolymerization of N-isopropylacrylamide and/or acrylamide and/or acrylic acid monomers and of (ii) layer silicates, and to the process for preparing them. The invention covers osmotically active hydrogel expanders containing said nano-composites, suitable for tissue expansion and the use of said materials for obtaining live skin.
