Abstract: This invention covers a novel method for the preparation of hydroxy polymer esters of amino, alkylamino and quaternary ammonium acids and their use in several fields of industry, including the use as additives in the manufacture of paper or paperboard. The esterification of the hydroxy polymer, preferably starch, is performed under semianhydrous conditions by heating homogenized mixtures of the hydroxy polymer and reagents.

Abstract: The invention relates to a process for the production of a sterol ester-rich composition. A sterol composition, a glyceride composition, a fatty acid alkyl ester and an esterification catalyst are combined to form a reaction mixture. Esterification of sterol(s) takes place in the mixture, providing sterol ester(s). The new process is rapid and has a high level of conversion. The invention also relates to a method for recovering food-grade sterol fatty acid ester(s) from a fat mixture.

Abstract: An easily water-soluble or water-dispersible sizing component, which contains cationized polyvinyl butyral or other equivalent cationized polyvinyl acetal, for the improvement of surface properties of paper or other equivalent web product. Cationized polyvinyl butyral can be prepared by cationizing polyvinyl butyral or by butyrating cationized polyvinyl alcohol. The sizing component typically contains 50-90% polyvinyl butyral or other corresponding polyvinyl acetal, and 10-50% of a softener, such as castor oil. The polyvinyl butyral containing sizing component can be used for example in the surface sizing of base paper of release paper and of inkjet paper or in the formation of a barrier layer on the paper surface.

Abstract: A cationic starch product, the making of it and its use. The starch product comprises starch (St) and a cationising reagent, which is made from choline or its synthetic equivalent, whereby the cationising reagent has reacted with a part of the hydroxyl groups of the starch according to the structure formula (VI) or (VII). The structure component A is a hydrocarbon chain. The substituents R are hydrogens; lower or higher acrylic alkly groups, substituted or unsubstituted cycloalklyl groups; substituted or unsubstituted aryl or heteroaryl groups; lower or higher alkyl groups or non-aromatic heterocyclic groups containing alkoxy groups or other hetero atoms.
