摘要

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 acyclic alkyl groups, substituted or unsubstituted cykloalkyl groups; substituted or unsubstituted aryl or heteroaryl groups; lower or higher alkyl groups or non-aromatic heterocyclic groups containing alkoxy groups or other heteroatoms.
