Abstract

Abstract : The novelty of the work: a water- and solvent-resistant coating was produced from a novel CO2 -based alcohol amine chain extender. Abstract : A five-membered cyclo-carbonate, prepared by cycloaddition reaction from CO2 and 1, 4-butanediol diglycidyl ether, was reacted with excessive diamine and formed a urethane group-containing new product. Structural characterization was performed for the new alcohol amine, which can be applied to the manufacture of polyurethane coatings as a chain extender. The new chain extender-based polyurethane coatings exhibited excellent water, salt, and solvent resistance and promising mechanical strength. Importantly, the unique performance of the prepared polyurethane coatings should be ascribed to the introduction of a hydroxyl group in the polyurethane molecule. The strengthened hydrogen bonding enlarged the cohesion of the polyurethane coatings and prohibited the solvents from permeating.
