Starch was preirradiated with cobalt-60 and then allowed to react with mixtures of acrylamide and N,N,N-trimethylaminoethyl methacrylate methyl sulfate (TMAEMA·MS) in a water solution. The graft copolymers resulting were purified and characterized,

Acrylonitrile (AN) was graft-polymerized onto gelatinized cationic starch (CS) possessing diethylaminoethyl ether groups by cerium (IV) initiation to give stable latexlike copolymer dispersions. Dispersions of the latex copolymers, having up to 50% g

In the reported experiments, starch polyampholytes (xanthated starch amines) that contained either diethylaminoethyl or 2-hydroxypropyltrimethylammonium ether and xanthate substituents were prepared, characterized, and evaluated as wet- and dry-stren

The reaction between starch xanthate and alkyl diepoxide formed gels in concentrated solution (6–8%) or turbid suspensions in dilute solution (0.1–1,0%); the gelling varied with the nature of the epoxide. The gel or suspension was dispersed and a

Starch 2-hydroxy-3-mercaptopropyl ethers of degree of substitution (DS) up to 0.34 were prepared as follows: starch was reacted with epichlorohydrin to give 3-chloro-2-hydroxypropyl ethers which were treated with thiosulfate to displace chloride ion
