Among possible routes towards isocyanate-free PUs, aminolysis of cyclic carbonates leading to polyhydroxyurethanes (PHUs) is one of the most promising pathways. Herein, we describe the solvent-free synthesis of shape memory PHU networks from diglycerol dicarbonate through reactive extrusion with varying amounts of primary and secondary triamines, Tris(2-aminoethyl)amine and Tris(2-(methyla-mino)ethyl)amine). Depending on the composition of the system, the glass transition temperature of the PHU networks can be finely tuned in the 20-40°C range and, consequently, affords shape memory recovery at body temperature. In addition, these networks revealed hydro-lysable over a few months and may find uses as bioresorbable templates for medical applications.< Réduire
