(A1) Offenbart wird eine polymere Zusammensetzung, enthaltend 0,1 Gew.-% bis 99,9 Gew.-% mindestens eines natuerlichen oder synthetischen Polymeren, wobei das natuerliche Polymere ausgewaehlt ist aus Polysacchariden oder Proteinen und das synthetische Polymere ausgewaehlt ist aus Polyvinylalkoholen und seinen Hydrolysaten, Ethylen-Vinylalkohol-Copolymeren, Copolymeren von PVOH mit Vinylacetat, Polyesteramiden, Polyvinylpyrrolidon und aus wasserunloeslichen biologisch abbaubaren Polymeren sowie aus Mischungen dieser natuerlichen oder synthetischen Polymere, 0,1 Gew.-% bis 99,9 Gew.-% mindestens eines Polyethylenoxids, darueber hinaus 0 Gew.-% bis 80 Gew.-%, bezogen auf die Gesamtmenge der Komponenten i) bis ii), ueblicher Hilfs- und Zusatzstoffe, ihre Herstellung und Verwendung und hieraus hergestellte Formkoerper.


DE 102007026719 A1 UPAB: 20090112 NOVELTY - Polymer composition (I), comprises: (a) at least a natural or synthetic polymer (0.1-99.9 wt.%), where the natural polymer is polysaccharide or protein and the synthetic polymer is polyvinyl alcohol and its hydrolyzates, ethylene-vinyl alcohol-copolymer, copolymer of polyvinyl alcohol with vinyl acetate, polyester amide, polyvinyl pyrrolidone or water-insoluble biologically degradable, polymers obtained from mixtures of these polymers; (b) at least a polyethylene oxide (0.1-99.9 wt.%); and (c) further auxiliary materials and additives (0-80 wt.%, based on the total quantity of (a) and (b)). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a molded body, manufactured using (I); (2) a molded body with carrier, comprising a layer of (I) on at least a part of the surface of the carrier; and (3) preparing (I), comprising dry mixing the components (a), (b) and optionally (c) in powder form in a mixer. USE - (I) is useful: for the manufacture of molded body; in the sanitary area of commercial, public or private rooms or in air-, land- or water-vehicles; as foil in household, commercial arrangements, or in agriculture; as socket foam, an adhesive foil, preferably protection foil or separating foil on an inorganic or organic carriers; and in the packaging area (all claimed), preferably in packaging materials for seed and nutrient. (I) is useful: to manufacture blend, agglomerate, granulate, micro-powder, molded parts, foils, profiles, spunbonded fabric and/or fibers; as compostable foil e.g. as mulch foil or a compostable coating e.g. paper or cardboard; as substrate in adhesive foils; and in baby panties, bags, sheets, bottles, cartons, dust bags, labels, pillowcase, protective clothing, hygienic article, handkerchiefs, toys and wiper. ADVANTAGE - (I) shows good biodegradability and water solubility, and is toxicologically harmless. (I) is reprocessible on a conventional polymer processing machine in connection with a pleasant haptic, which provides a pleasant skin feeling, and has a storability of at least 6 months.
