摘要： The invention provides a multi-arm block copolymer for use in delivering a variety of bioactive agents. The copolymer of the invention contains a central core from which extend multiple (3 or more) copolymer arms. Each copolymer arm possesses an inner polypeptide segment and an outer hydrophilic polymer segment. Thus, the overall structure of the copolymer comprises an inner core region that includes the central core and the inner polypeptide segment, while the outer core region is hydrophilic in nature. The multi-arm copolymer of the invention is particularly useful for delivery of biologically active agents that can be entrapped within the inner core region.

摘要： A dihydroxyphenyl cross-linked macromolecular network is provided that is useful in artificial tissue and tissue engineering applications, such as artificial or synthetic cartilage. The network is made by first providing a polyamine or polycarboxylate macromolecule (having a plurality of amine or carboxylic acid groups respectively attached along the length of the molecule), reacting this macromolecule with a hydroxyphenyl compound having a free carboxylic acid group in the case of a polyamine or a free primary amine group in the case of a polycarboxylate, and substituting the hydroxyphenyl compound onto the macromolecule via a carbodiimide-mediated reaction pathway to provide a hydroxyphenyl-substituted macromolecule. This macromolecule is then linked to other such macromolecules via an enzyme catalyzed dimerization reaction between two hydroxyphenyl groups attached respectively to different macromolecules under metabolic conditions of temperature and pH. In a preferred embodiment, the macromolecular network is made up of tyramine-substituted hyaluronan molecules that are linked by dityramine bonds to provide a stable, coherent hydrogel with desired physical properties. A method of preparing such a network is also provided.

摘要： The present invention relates to a film comprising copolymers of ethylene and of an unsaturated epoxide and comprising quinones grafted onto these copolymers. The quinones are subsequently reduced (activation) to become oxygen absorbers. According to an advantageous form of the invention, it is possible, in addition to the quinones, to graft a product which results in the appearance of a hydroxyl functional group (proton donor) and optionally introduces other hydroxyl functional groups. This improves the activation of the quinone functional groups. The present invention also relates to structures comprising at least one barrier film to oxygen and at least the preceding film. The present invention also relates to a packaging comprising the preceding structure, in which, starting from the inside of the packaging and proceeding towards the outside, first the oxygen-absorbing film is encountered, followed by the barrier film to oxygen.
