[Polymer materials for biomedical purposes obtained by radiological methods. II. Radiation polymerization of acrylamides and N-vinylpyrrolidone].

The radiation polymerization of acrylamide and N-vinylpyrrolidin-2-one in aqueous solutions has been investigated. The effect of the monomer concentration as well as the dose rate of the ionizing radiation on the process has been determined. The radical mechanism of the polymerization process has been confirmed experimentally. The effect of the individual transient species of the water radiolysis on the initiation of the polymerization process as well as the changes of the molecular weights of the arising polymers have been investigated. The dependence of the galation dose of the system on the monomer concentration has been determined.
