Polysaccharides containing aromatic aldehydes and their derivatization via amine-aldehyde interactions. |
摘要 |
<p>A polysaccharide derivative having the structure Sacch-O-Z-Ar-CH=N-Y or Sacch-O- @-Z-Ar-CH=N-Y, where Sacch-O-represents a polysaccharide molecule; where Z is -CH2- @@-(CH2)m-O- when Ar is a divalent aromatic group or -(CH2)n.- when Ar is a divalent aromatic group other than a phenolic aromatic group and Y is a monovalent group derived from a water-soluble substituted or unsubstitited aromatic compound containing only one free primary amine group; where Z is -CH2- @@- (CH2)m-O- or -(CH2)n- when Ar is a divalent aromatic group and Y is a monovalent group derived from a water-soluble substituted or unsubstituted aliphatic or cycloaliphatic compound containing only one primary amine group; where Z is -CH2- @@- (CH2)m-O- or -(CH2)n- when Ar is a divalent aromatic group and Y is 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.</p> |
