Latest Patents
One of Ketola's latest patents is focused on a process for the preparation of a stable, chlorine-free modified starch. This invention is particularly useful in paper coating and sizing. The process involves degrading starch through catalyzed hydrogen peroxide oxidation and stabilizing it via acetyl esterification, combined with crosslinking of the starch. Another significant patent is a method for internal sizing of paper using cationic starch. In this method, the starch is cationized with a mixture of epichlorohydrin, trimethylamine, and mono- or dimethylamine or N,N,N',N'-tetramethylethylenediamine. This cationizing process results in a higher molecular size of the starch, which positively affects dewatering on the paper machine forming wire.
