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

The effect of concentration, reactant ratios, temperature, and starch pretreatment on grafting of acrylonitrile onto starch were studied. Grafting was efficient at high concentrations (8–12% starch) when granular starch was used. The molecular weig

Thiol starches of degree of substitution (D.S.) 0.005–0.162 were prepared by displacing starch tosyloxy groups with xanthate and treating the resulting xanthate esters with either sodium hydroxide or sodium borohydride. Acrylonitrile, styrene, acry

Conditions for the precipitation of sodium starch xanthate as the zinc salt were determined to be: xanthate degree of substitution greater than 0.02 and zinc ion concentration of 0.005–0.015-M. As xanthate ion concentration is increased, less zinc

A small pilot-plant batch process for the encapsulation of pesticides with crosslinked starch xanthate (starch xanthide) has been developed. Multipound quantities of several encapsulated pesticides have been prepared that have slow-release properties
