METHOD OF MANUFACTURING AN ADJUSTABLE-VISCOSITY CATIONIC STARCH

摘要

The invention relates to a method of preparing an adjustable-viscosity cationized starch in which, in a process step in the presence of 10 to 35 wt. % water and preferably 0.01 to 2.00 wt. % of a finely-divided silica and/or silicate (in each case relative to the total amount of mixture) the starch is homogenized with an alkaline oxide, hydroxide, silicate aluminate or mixtures thereof, an alkylene epoxide and a peroxo compound or a mixture of at least two peroxo compounds and then boiled in known manner at the desired time.
