Abstract: The invention relates to thermoplastically shapeable mixtures of COOH group-containing polymers dissolvable in an aqueous neutral or aqueous-alkaline medium with fillers. Such mixtures can be processed by thermoplastic shaping to moulded articles, which are dissolvable after use. The invention also relates to suitable copolymers for this purpose and the use thereof for the production of moulded articles.

Abstract: The invention relates to an adhesive film, such as a label system or the like, formed from a film of a copolymer of acrylic and/or methacrylic acid, as well as acrylate and/or methacrylate soluble in aqueous alkali and an adhesive applied to the film and which is soluble in aqueous alkali. The adhesive film as a whole is dissolvable in the aqueous alkali and is suitable, particularly in colored printed form, for water-resistant labels, but which are easily removable in aqueous alkali. The copolymer can be recovered again from the aqueous system by a precipitation with acid.

Abstract: The invention relates to amino group-containing polymers, which are produced by the polymerization of acrylates with aminoacrylates in the forms of esters of acrylic or methacrylic acid with amino alcohols. Polymers of this type are insoluble in the neutral to basic aqueous medium, but are soluble in the acid medium. They are particularly suitable for the production of colostomy bags.

Abstract: The invention relates to polymers, which are produced through using organic acids, together with the products obtained therefrom. The polymers and the products obtained therefrom are insoluble in water, but soluble in an alkaline medium. There are numerous interesting possible uses for the polymers.

Abstract: Polymers formed by incomplete esterification of the hydroxy groups of a water-soluble polymer such as polyvinyl alcohol, amylose or dextran with a pharmacologically acceptable mono- or di-carboxylic acid to an extent sufficient to render the polymer water-insoluble although still water-swellable, are biodegradable. They are useful for the formulation of pharmaceutical compositions for parenteral administration, particularly in the form of injectable fine particles in which a drug is intimately mixed with or encapsulated by the polymer.

Abstract: In a method for the production of corrosion-inhibiting coatings on metallic surfaces, a mixture consisting of a phenol, low molecular condensation products of formaldehyde and ammonia or amines and a wetting agent, which is chemically reactive with the starting materials, is applied onto the surface to be coated and is cured under heat. The mixture is applied in the form of a solution, dispersion or powder.

Abstract: Bone replacement or prosthesis anchoring material on the basis of sintered calcium phosphates which consists of a mixture of calcium phosphates with low or high-molecular-weight organic substances. More specifically, the anchoring material consists of a mixture of calcium phosphates composed of CaO and P.sub.2 O.sub.5 in a quantitative ratio of 2:1 to 4:1 with biodegradable polymers in a ratio of 10:1 to 1:1 of phosphate to polymer and is implantable as a solid body. A method for the production of the material wherein calcium phosphate with a porosity of 15 to 30 volume percent is used and its pores are filled by impregnation with polymer material.
