ABSTRACT:
Starch is prepared for use in the manufacture of paper products by reacting an alkaline hypochlorite oxidized starch with ammonium persulfate. The treatment provides a starch product which when pasted at high temperatures will degrade to give a low viscosity material. The process includes the steps of slurrying lightly oxidized starch in water and further oxidizing the starch with ammonium persulfate. When this starch is suspended in water and heated to pasting, it shows lower viscosities than other starches of comparable starting viscosities.
