ABSTRACT:
A derivatized graft polymer of a polysaccharide, a crosslinked graft polymer of a polysaccharide, and a derivatized and crosslinked graft polymer of a polysaccharide are prepared. The derivatized polymer has the structure Sacch-g-[(M--CH.dbd.N--Y).sub.x -g-[(M).sub.q ]; the crosslinked polymer has the structure Sacch-g-[(M--CH.dbd.N).sub.z -P].sub.w -g-[(M).sub.q ] or Sacch-g-[(M--CH.dbd.C).sub.z -P].sub.w -g-[(M).sub.q ]; the derivatized and crosslinked polymer has the structure Sacch-g-[(M--CH.dbd.N--Y).sub.x ]-g-[(M--CH.dbd.N)-P]-g-[(M).sub.q ] or Sacch-g-[(M--CH.dbd.N--Y).sub.x ]-g-[(M--CH.dbd.C).sub.z -P].sub.w -g-[(M).sub.q ]. Sacch represents a polysaccharide such as starch, gum, or cellulose; g-represents a graft; M represents one or more ethylenically or allylically unsaturated monomers, at least one of which contains an acetal or aldehyde; P represents a multivalen residue from a reagent containing more than one primary amine group or ketone group; --N.dbd. represents the group formed when one primary amine group of P reacts with the acetal or aldehyde group of the monomer repecting unit M; 13 CH.dbd. represents the group formed when one of the ketone groups of P reacts with the acetal or aldehyde group of the monomer repeating unit M; x is at least 1; z is at least 2; w is at least 1; and q is 0 or greater.
