Abstract A method for preparing a cationic cross-bonding reagent wherein the amount of cross-bonding impurities is determined and a certain quantity of a cross-bonding agent is added. This cationic cross-bonding reagent is used in a process for preparing cationic cross-bonded starches with tailor-made viscosity and excellent viscosity stability. Products with tailor-made viscosity can be used according to their need in specific applications in the wet-end of papermaking.
