FIELD: medicine.
SUBSTANCE: invention refers to medicine. There are described methods for preparing biomaterials to be used as a woven sealant, complete sets containing precursors for preparing the biomaterials, and the resultant biomaterials. The biomaterials are prepared of the composition containing at least molecules of the first and second precursors, wherein: i) a molecule of the first precursor is a polymer of poly(ethylene glycol) having x nucleophilic groups specified in a group consisting of thiol or amine groups, wherein x is equal to 2 or more, preferentially 3, 4, 5, 6, 7 or 8; ii) a molecule of the second precursor is described by general formula: A-[(C3H6O)n-(C2H4O)m-B]i, wherein m and n represent integers within the range 1 to 200, i is more than 2, preferentially 3, 4, 5, 6, 7 or 8, A represents a junction point, B represents a conjugated unsaturated group.
EFFECT: biomaterials are able to glue tissue surfaces together quickly without complication of common therapy.
