METHOD FOR OBTAINING OF OBJECTS FROM BIOCOMPATIBLE HYDROGEL FOR APPLICATION IN MEDICINE, NAMELY IN OPHTHALMOLOGY Russian patent published in 2017 - IPC A61F2/14 C08F6/06 C08L33/20 

Abstract RU 2638849 C2

FIELD: medicine.

SUBSTANCE: method comprises the follosing steps: (i) preparation of a polymer solution by dissolving an acrylonitrile copolymer and an anionic group-containing olefinically unsaturated comonomer in an aprotic solvent, optionally in the presence of a precipitant, (ii) forming and starting of transition of the polymer solution obtained in step (i) into gel in a template consisting of a material containing said precipitant, or from a material permeable to said precipitant, (iii) immersion of the object obtained in step (ii) in precipitate during gel formation. The invention also relates to objects from a biocompatible hydrogel obtained by this method.

EFFECT: obtaining of objects from a biocompatible hydrogel with improved optical, physico-chemical and biological properties, and having excellent dimensional stability.
