    摘要： The present invention provides a process for preparing aqueous solutions of NCO group blocked resins having polyimide structures and optionally, polyamide structures. The process comprises the steps of preparing a polymer from at least one polyisocyanate, at least one tricarboxylic monoanhydride and/or at least one tetracarboxylic anhydride, and optionally, tricarboxylic acids, tetracarboxylic acids and/or dicarboxylic acids, at least one NH-functional lactam and/or 3,5-dimethylpyrazole and/or butanone oxime. The reaction mixture is subsequently reacted with a base, and the resulting resin is dissolved in water. The resins provide high-grade, highly flexible coatings having the excellent properties and chemical resistance typical of polyamideimides.

    摘要： The present invention relates to biomedical foam articles for the wound sector which are formed by spraying a polymeric dispersion onto a wound. The polymeric dispersion being sprayed onto a wound surface forms a three-dimensional body which conforms to the spatial shape of the wound and which, as well as covering the wound surface, ensures a complete and accurately fitted packing of the wound in the depth dimension as well as the other dimensions. The biomedical foam articles of the present invention are particularly useful for treating chronic wounds.

    摘要： The present invention relates to aqueous copolymer dispersions containing A) one or more hydroxy-functional copolymers synthesized from a) one or more OH-free (meth)acrylic esters and/or vinylaromatics, b) one or more hydroxy-functional (meth)acrylic esters, c) one or more ionic and/or potential ionic monomers capable of free-radical copolymerization, and d) one or more optionally monomers other than components a) to c) that are capable of free-radical copolymerization, and B) one or more hydroxy-functional polycarbonate polyols as reactive diluent. The present invention also relates to a process for preparing these aqueous copolymer dispersions and to their use in coating compositions.
