ABSTRACT:
A process whereby a gelatinized starch having a cationic reagent chemically bound to the starch backbone and a reduced viscosity is prepared by (1) gelatinizing starch and substantially simultaneous with gelatinization reacting said treated starch with an alkyl or alkenyl amine and a water soluble oxidant or (2) simultaneously reacting an alkyl or alkenyl amine and a water soluble oxidant with a gelatinized starch. The process is conducive to the on-site preparation of a thinned cationic starch derivative which can be utilized without additional treatment as a papermaking additive, textile size, waste water treatment, tailing flocculent, etc.
