POLYACRYLAMIDE HYDROGEL-BASED MATERIAL FOR MEDICAL PURPOSES AND METHOD FOR PRODUCING SAME |
摘要 |
A material for medical purposes based on polyacrylamide hydrogel and containing: 0.9-8.2 wt% acrylamide, 0.1-1.8 wt% N-N'-methylenebisacrylamide, 0.1-2.0 wt% hyaluronic acid, and up to 100 wt% water. In one embodiment of the present method, the proposed material is produced by copolymerization of the above-mentioned components in an inert gas atmosphere in the presence of a peroxide polymerization initiator at a temperature of 69-74°C over a period of 16-19 hours. In another embodiment, hyaluronic acid hydrogel is mixed in an inert gas atmosphere to a homogeneous state with a polyacrylamide gel suitable for medical use which is produced from the relevant amounts of acrylamide and N-N'-methylenebisacrylamide and water in the presence of a peroxide polymerization initiator. |
