FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to medicinal hydrogel polymer materials, used as a base for the creation of polymer implants and products, contacting with blood. Described is a non-porous hydrogel material based on a modified polyvinyl alcohol, which contains unsaturated radicals in side chains, obtained by polymerisation at 0-250°C in a solution or in polymer powder sintering at 100-180°C. Also described is a combined material, containing a matrix of the porous hydrogel polymer material and reinforcing filler, filling the matrix, of the non-porous hydrogel material obtained by the said method.
EFFECT: materials are liquid-impermeable, possess biocompatibility, high strength characteristics and high stability at heating.
