Evaluation of the film and adhesive properties of some block copolymer polyhydroxypolyamides from esterified aldaric acids and diamines

摘要

A number of structurally different block copolymer polyhydroxypolyamides (PHPAs), produced by condensation polymerization of activated aldarates with 1 degrees diamines, were evaluated for their water and methanol solubility and film-forming and adhesive properties. The polymers are composed of a single aldaric acid and a single diamine unit, a single aldaric acid and two diamine units, two aldaric acids and a single diamine unit, or two aldaric acids and two diamine units. The aldaryl monomer units in the polymers were derived from D-glucaric, xylaric, and galactaric (mucic) acids. A number of alkylenediamines and heteroatom (oxygen and nitrogen)-containing diamines were employed as comonomers. (C) 2000 John Wiley & Sons, Inc. [References: 20]
