Radiation gelation of hydrogels and their applications

In the report the results of studies on the application of radiation technique to the production of biomaterials such as vascular prostheses with increased hydrophilicity and improved tightness, a special type of ocular insert device containing the drug against glaucoma as well as different kinds of wound covering materials have been presented. These materials have been obtained on the base of radiation crosslinked synthetic polymers. As source materials appropriate aqueous solutions of monomers were used. In the first part of this report the results concerning the radiation polymerization and crosslinking of N-vinylpyrrolidone in aqueous solutions in the presence of different additives (O2, N2O, CH3OH) are presented.
