Dry chemical process for grafting acrylic and methyl acrylic ester and amide monomers onto starch-containing materials

摘要

Acrylic monomers are grafted onto starch-containing materials by a novel dry state process in which small amounts of peroxides chemically initiate the free radical reaction. Since the process is dry and the resultant products contain no contaminants, it is unnecessary to isolate, wash, and dry them before use. The products are useful in the paper and mineral separation industries.
