FIELD: medicine; chemistry.SUBSTANCE: invention relates to curable compositions for treating open wounds. Curable composition apportioned between at least one part A and at least one part B of composition, where at least one part A comprises: (i) polydiorganosiloxane polymer including alkenyl-containing links, at least one part B includes: (ii) one or more SiH-containing polymer, including at least one or at least two SiH links or groups per molecule; and composition also contains: (iii) a catalyst for curing by linking polydiorganosiloxane polymer containing alkenyl-containing links (i) to SiH-containing polymer (ii), and optionally (iv) gas-forming agent selected from any gas-releasing agent, as a component of reaction or during curing reaction; where polymer (ii) is absent in part A and polymer (i) is absent in part B of composition or segment includes a trace amount of polymer (i), expressed as molar ratio (Si-H link or group)/(alkenyl link or group) greater than or equal to 2,000. Invention also describes method for preparing composition, method for sterilisation of composition, method of obtaining an elastomer, elastomer, medical or non-medical use of composition, a device for dispensing composition, kit for therapy of wounds.EFFECT: curable composition, capable of withstanding radiation dose sufficient for sterilisation, without its decomposition.16 cl, 15 dwg, 6 tbl, 9 ex |
