ABSTRACT:
Polymers of glucaric or xylaric acid with diprimary amines containing at least one heteroatom in the main chain form films when cast from aqueous solution and show adhesive properties. Unexpectedly, analogous polymers prepared using galactaric acid, an isomer of glucaric acid, do not form satisfactory films when cast from aqueous solution and exhibit poor or no adhesive properties. Copoly(aldaramides) comprising galactaric acid residues and either glucaric acid or xylaric acid residues, when prepared by reacting an equivalent weight of an activated galactarate with a product formed by reaction of two equivalents of a diprimary heterohydrocarbylenediamine with one equivalent of either an activated xylarate or glucarate also afford film-forming polymers which exhibit adhesive properties.
