A method for internal sizing of paper using cationic starch is provided. The starch used is cationized with a mixture of epichlorhydrin, trimethylamine, and mono-or dimethylamine or N,N,N',N'-tetramethylethylenediamine. Cationizing results in a higher molecular size of the starch, which has e.g. a beneficial effect on dewatering on the paper machine forming wire. |
