Abstract

AbstractGraft copolymers of tuber and legume starches with polyacrylonitrile (PAN) have been prepared. Molecular weight, frequency of grafting, and adsorbencies of saponified products have been investigated. Yield and add‐on of granular graft copolymers are dependent on the source of starch. Parameters for gelatinized graft copolymers are almost constant. Yield, add‐on, molecular weight and adsorbencies are different for the granular graft copolymer of garden pea starch. On pretreatment up to 70°C, these parameters are comparable with those of other starch graft copolymers.
