Starch can be converted to starch-g-poly(methyl acrylate) (S-g-PMA) latexes in a number of weight proportions, (S to PMA), that will give excellent stabilization of soil particles to water. To extend the study of additives for use as soil stabilizers

Three types of polyanionic starch derivatives were prepared: carboxymethyl starch, starch-g-poly(acrylic acid) and hydrolyzed starch-g-polyacrylonitrile. Each derivative was prepared at five levels of anion content, and the milliequivalent of carboxy

Starch derivatives were compared with polyvinyl alcohol and with polyvinyl acetates by wet sieving techniques to obtain an indication of soil stabilizing potential. Certain benzyl ethers of both starch and hydroxyethylated (HE) starch exhibited stabi

The solid, water-insoluble sorbent called Super Slurper that swells in water is a base hydrolyzed starch-polyacrylonitrile graft copolymer in which the nitrile functionality has been converted to a mixture of carboxamide and alkali metal carboxylate.

Cationic starch-g-polymer latexes stabilize soil particles to water. To extend the study of such utility of starch latexes we prepared starch-g-poly(methyl acrylate) (S-g-PMA) and cationic starch-g-poly(methyl acrylate) (CS-g-PMA) latexes by the ceri

Starch-polyacrylonitrile (S-PAN) graft copolymer consisting of one part starch and one part polyacrylonitrile (M. W. 794,000) was hydrolyzed with aqueous KOH at 80 and 100°C to polyelectrolytes containing carboxyl and amide functionality but void of

Three starch–polyacrylonitrile (S–PAN) graft copolymers containing ratios of S:PAN of 1:1.90, 1:1.16, and 1:0.64 were prepared by graft polymerization of acrylonitrile onto gelatinized starch. A fourth graft, made from granular starch, had an S:P

Tertiary cationic starch. quaternary cationic starch and cationic starch graft copolymers were each prepared at several levels ofcation content. Together with some commercial cationic starches. these materials were assayed by wet sieving to determine
