A hybrid methodology is used to combine the favorable properties of non-isocyanate polyurethanes (NIPUs) in side chains with poly(methacrylates) as backbone into thermoset resins hydroxyurethane linkages (HNIPU)s. Using NIPUs avoids use toxic isocyanates poly(urethane) segments. The synthesized from cyclic carbonated copolymer templates derived atom transfer radical polymerization (ATRP) an alk...
