    摘要： Polymer composite materials are disclosed containing one or more chemical scavengers. The polymer composites are porous and are configured to be contacted with a liquid for removing trace amounts of metals, proteins, polypeptides, polyphenols, other organic compounds, and the like. In order to produce the porous composite polymer product, one or more chemical scavengers are combined with thermoplastic polymer particles and sintered into a shape. The polymer particles act as a binder trapping or encasing the one or more chemical scavengers in the porous structure.

    摘要： The invention describes a method for producing a foam moulding from poly(meth)acrylimide, an adhesion promoter or an adhesion promoter mixture and optional auxiliaries, comprising the following steps: grinding a polymeric moulding made of poly(meth)acrylamide, coating the grindings obtained in the preceding step with an adhesion promoter, introducing the coated grindings into a mould, optionally adding the auxiliaries, heating the mould, cooling the mould below the foaming temperature, and demoulding the foam moulding. The resulting foam moulding has outstanding mechanical properties and is suitable for applications including as a component in the production of space, air, water and land vehicles.

    摘要： A porous polyimide is obtained by pulverizing a foam product of a polyimide precursor. Particularly, the foam product of the polyimide precursor is a product of heating the polyimide precursor for foaming with microwave radiation and has the imidization ratio of 10 to 90%, and is preferably a foam product including a tetracarboxylic acid component, which contains 50 mol % or more of biphenyltetracarboxylic acids and is monoesterified and/or diesterified in parts with a lower aliphatic primary alcohol with the number of carbon atoms of 4 or less, and a diamine component containing 90 mol % or more of an aromatic diamine, and being a monomer salt of which the ratio of the tetracarboxylic acid component and the diamine component is approximately 2:1 and in a solid form dispersed at molecular level.

    摘要： A bone defect filler for implantation in a bone defect of a patient includes a particulate polymer distributed within a polymeric binder. The particulate polymer includes a plurality of particles, which may have substantially the same material composition as the polymeric binder. The particles of the particulate polymer may be formed in a variety of shapes and/or sizes to provide the bone defect filler with improved pore interconnectivity, material expansion and contamination characteristics, while maintaining sufficient mechanical strength and handling characteristics for bone repair applications. The bone defect filler also provides the flexibility to be molded or shaped in situ to fill the bone defect.
