ABSTRACT:
A polysaccharide derivative having the structure Sacch--O--Z--Ar--CH.dbd.N--Y or ##STR1## where Sacch-O- represents a polysaccharide molecule; Z is --(CH.sub.2).sub.n -- or ##STR2## Ar is a divalent aromatic group; Y is (a) a monovalent group derived from a water-soluble substituted or unsubstituted aromatic compound containing only one free primary amine group, or (b) a monovalent group derived from a water-soluble substituted or unsubstituted aliphatic or cycloaliphatic compound containing only one primary amine group, or (c) a multivalent group derived from a water-soluble protein containing more than one primary amine group; n is one or greater; and m is zero or greater, is prepared by first modifying the polysaccharide with a reagent to introduce free aromatic aldehyde groups and then reacting with a suitable amine-containing reagent. The siloxane-containing starch derivatives are useful in glass forming size compositions.
