| Abstract: | It has been shown that when a mixture of starch with sodium hydroxide and monochloroacetic acid is irradiated, the carboxymethylstarch (CMS) obtained consists of fractions with high levels of carboxymethyl groups and fractions with a predominant content of carbonyl groups, and when this mixture is subjected to mechanical treatment a far-reaching rearrangement of the structure of the starch takes place with its homogeneous interaction with the reagents to form CMS.Institute of Physical Organic Chemistry, Academy of Sciences of the Belorussian SSR, Minsk.
