Abstract
A glyoxylate starch may be formed by dispersing a starch in a liquid to form a starch slurry. The starch may be one or more of a cationic starch, nonionic starch, and an anionic starch. 2-chloracetamide is added to the starch slurry mixture to form a first reaction mixture. The temperature of the first reaction mixture may then be raised, and then cooled to form a modified starch, and glyoxal may be added to the modified starch solution to form a second reaction mixture that may then be stirred to produce a glyoxylate starch.
