Abstract RU 2572849 C1

FIELD: chemistry.

SUBSTANCE: method relates to biodegradable material production. Biodegradable material, which is a chemical bond-crosslinked product, formed by a multivalent compound A, which includes 3 or more functional groups X, selected from a group consisting of a hydroxyl group, a thiol group and an amino group, and a multivalent compound B, which includes 3 or more functional groups Y, selected from a group consisting of a carboxyl group, an isocyanate group and a thioisocyanate group, where the chemical cross links are formed via condensation reaction of said functional group(s) X and said functional group(s) Y, where the value (y+z)/(x+z) ranges from 1.2 to 4.0, if MA≥MB, and the value (x+z)/(y+z) ranges from 1.2 to 4.0, if MA<MB, where x denotes the number of functional groups X not involved in the condensation reaction with said functional groups Y, y denotes the number of functional groups Y not involved in the condensation reaction with said functional groups X, z denotes the number of said cross links, MA denotes the weight-average molecular weight of said multivalent compound A and MB denotes the weight-average molecular weight of said multivalent compound B. The invention also discloses a vessel embolisation material, an anti-adhesive material, a wound-dressing material, a blood-staunching material and a material which prevents involuntary urination.

EFFECT: material has high compression force, high degree of recovery, high complex modulus of elasticity and short gel time.
