FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing biologically compatible gel which is thickened with cross-linked polymer by cross-linking a given amount of at least one biologically compatible natural polymer in a solution by adding a defined amount of cross-linking agent, an additional amount of polymer with molecular weight over 500000 dalton in a solution, in which the reaction mixture is diluted to reduce concentration of polymer in the solution, and the cross-linking reaction is stopped by removing the cross-linking agent.
EFFECT: gel and its use for separating, replacing or filling biological tissue or for increasing volume of such tissue, or supplementing or replacing biological fluid.
