PREPARAT FOR ABSORPSJON AV VANDIGE VAESKER OG FREMGANGSMAATE VED FREMSTILLING AV SAMME.

摘要

Absorbent polymeric compositions are prepared by graft polymerizing acrylonitrile onto flour or other starch-containing substrates and then subjecting the flour-polyacrylonitrile graft copolymers to alkaline saponification. Compositions prepared from gelatinized flour absorb from 1800-3000 times their weight of deionized water.
