Hydrophobilization of Furan-Containing Polyurethanes via Diels-Alder Reaction with Fatty Maleimides.

ABSTRACT: We describe new hydrophobic functionalized linear polyurethane resins by combining N-alkyl maleimides via the Diels-Alder reaction with linear furan-modified polyurethanes. This procedure provides the opportunity for the post-polymerization-functionalizing of polyurethanes. Access to furan-bearing polyurethanes is achieved via the reaction of a furan-containing diol, polyethylenglycol (PEG), and different diisocyanates. The furan-containing diol is obtained from the reaction of furfurylamine and two equivalents of hydroxyalkyl acrylate. The resulting furan-bearing polyurethanes are reacted with fatty amine-based N-alkyl maleimides. The maleimide and furan functionalities undergo a Diels-Alder reaction, which allows for the covalent bonding of the hydrophobic side chains to the polyurethane
