Abstract: A polymer dispersion or solution containing a hydrophobic polysaccharide, which is dispersed or dissolved in liquid phase, and palsticizer composition of the polysaccharide, whereby at least 10% by weight of the plascitizer composition is formed from alkenyl succinic anhydride. The invention also relates to the preparation of polymer dispersions and solutions and to the films and coatings produced from them. The dispersions according to the invention are stable, and coating with excellent film-forming properties can be prepared from them.

Abstract: A process for manufacturing transglycosylation products. According to the process, a starch derivative is reacted at acidic conditions with an alkanol containing 1-6 hydroxyl groups and the reaction product is recovered as such or it is subjected to further processing. According to the method, the transglycosylation reaction between the starch derivatives and the alkanol is carried out in a reactive extrusion process, whereby the reaction can essentially be performed in the absence of liquid media at high yield. The invention also relates to new transglycosylation products of starch derivative, containing anions derived from a phosphorus-containing acid, which are chemically bonded to the product.

Abstract: A method for manufacturing a board product made up of at least two layers, and a multilayer board product. According to the method, the board webs (4, 5, 6) forming the layers are bonded together by gluing. According to the invention, at least one of the webs is treated mechanically by compression so that in the web surface there form permanent deformations projecting from the web surface, and the layers are glued together by using a starch-based adhesive, which is applied at a solids content over 45% to the layers to be bonded. The adhesive having a high solids content dries and bonds rapidly to the surfaces to be joined, even without additional heating. Since the adhesive contains little or no water, no after-bending or flattening of the middle layer occurs in the bond.

Abstract: The invention relates to novel transglycosylation products and their preparation. The transglycosylation products according to the invention are prepared from starch derivatives, such as esters or ethers of starch. The products are obtained by reacting a starch derivative with an alcohol in the presence of an acid catalyst. The forming product is separated by precipitation or by removing any unreacted alcohol by evaporation. In the products according to the invention the good properties of starch derivatives, such as the excellent water resistance of esters, are combined with the versatility of transglycoside products. The products can be used as adhesives, in which case they are formulated, for example as hot-melt adhesives, and as comonomers, prepolymers or macroinitiators in the preparation of polymers.

Abstract: The invention relates to an adhesive formulation that comprises a starch-based adhesive dissolved in water. According to the invention the adhesive is made up of a native starch transglycosylation product and the solids content of the adhesive formulation is at least 45% by weight. The invention also relates to a method for preparing such adhesive formulations and to the use of the adhesives.

Abstract: The invention relates to a new process for preparing polymer dispersions. According to the invention, a mixture is first formed of a polymer component, a plasticizer, dispersion auxiliaries and water, the mixture is then heated to approximately 20 to 100° C. in order to form a paste-like composition, and the paste-like composition is dispersed in water. The dispersion obtained according to the invention can be used for coating paper or board, as a primer, as a component in adhesives, paint or lacquer, and it is also suited for the manufacture of cast films and for use as a binder in materials based on cellulosic fibers.

Abstract: The invention concerns dietary fat compositions that contain the hydroxy acid or dicarboxylic acid or amino acid esters of a phytosterol and/or phytostanol, or the mixed esters formed with the alcohols, polyols or polyol (C2 . . . C22)-fatty acid esters of dicarboxylic acids or hydroxy acids, or the (C2 . . . C22)-fatty acid esters of hydroxy acids.

Abstract: The invention relates to a mammography device, having a frame column (3) comprising a slide (2) mounted vertically (Z) slidingly onto bearings, into the horizontal axis of which the photography head (1) is pivotally mounted onto bearings. According to the invention, the control device (10), the photography head (1) being tilted, guides the hoisting mechanism (M1) of the slide (2) according to a preset program and to the observed angle of inclination (.OMEGA.) in such a way that the center point of the support plate (6) in the photography head is at essentially the same height above the support (20) at the end of the tilting movement.
