    摘要: The present invention relates to a process of producing a composition for medical purposes, in particular for wound treatment, comprising the steps of:
    i. preparing a mixture comprising a superabsorbent polymer, an isocyanate-terminated prepolymer and water,
    ii. allowing the prepolymer to react with one or more components of the mixture to obtain the composition,
    wherein the superabsorbent polymer is a cross-linked polyacrylate and wherein the isocyanate-terminated prepolymer contains polyalkylene oxide units and is a branched molecule having at least three arms. Moreover, the present invention relates to the composition obtainable by the aforementioned process. Use of said composition in medicine and as wound dressing material is also a subject of the present invention. For example, the composition may be used as an atraumatic wound contact layer, which may absorb excess moisture from the wound and release moisture to the wound as required. Thereby, the composition may create a moist wound environment supporting the healing process and may effectively prevent maceration and drying of the wound. In particular, the composition may have a high absorption capacity.
