Abstract

Graphical abstract: Highlights: Synthesis of series of isocyanate-free poly(hydroxyurethane)s. Comparison to reference polyurethane with analogous structure. Characterization of physico and thermo-mechanical properties. Study of adhesion properties of wood, glass and aluminum. PHUs exhibit outstanding adhesion properties compared to PUs. Abstract: A series of poly(hydroxyurethane) (PHU) materials were synthesized by step growth polymerization of cyclic carbonates and diamines. Trimethylolpropane tris-carbonate and various poly(propylene oxide) bis-carbonates were copolymerized with EDR-148 or 1, 3-cyclohexanebis(methylamine) (CBMA). Thermal, mechanical and thermo-mechanical properties of PHU materials were characterized by DSC, TGA, durometer, dynamometer and DMA. Moreover, for the first time, we report adhesive properties of PHU synthesized without isocyanate on wood, aluminum and glass supports. All these properties were compared to reference polyurethane materials, synthesized from poly(propylene oxide) triol polymerized with hexamethylenediisocyante (HDI) or 1, 3-bis(isocyanatomethyl)cyclohexane (CBMI), in order to compare the materials properties of similar chemical structure. PHUs exhibit outstanding adhesion properties due to the presence of hydroxyl groups hanging off the main polycarbonate chain.
