    Structurally Ordered NIPUs via Catalyst-Free Synthesis with Hard Segments Based on Erythritol and a Long-Chain Diamine

    Structurally Ordered NIPUs via Catalyst-Free Synthesis with Hard Segments Based on Erythritol and a Long-Chain Diamine por Edyta Hebda, Karolina Wróbel, Aleksandra Cieślik, Kinga Szołdrowska, Jan Ozimek, Paulina Zając, Konstantinos N. Raftopoulos, Krzysztof Pielichowski

    Publicado 2025-07-01

    A series of linear isocyanate-free polyurethanes (NIPUs) were obtained via the aminolysis of erythritol dicarbonate (EDC) with polyethers (diamino-PEG, diamino-PPO, and diamino-PEG/PPO) and 1,12-diaminododecane (DADD), which acts as a chain extender to form hard segments. The obtained NIPUs containe...

    Isocyanate-free fabrication of sustainable polyurethane/POSS hybrid materials with tunable thermo-mechanical response

    Isocyanate-free fabrication of sustainable polyurethane/POSS hybrid materials with tunable thermo-mechanical response por Piotr Stachak, Izabela Łukaszewska, Jan Ozimek, Konstantinos Nikolaou Raftopoulos, Artur Bukowczan, Edyta Hebda, Carlos Bujalance Calduch, Krzysztof Pielichowski

    Publicado 2024-01-01

    This work reports on the synthesis of non-isocyanate polyurethanes (NIPUs) obtained via the polyaddition of diamines: dimer fatty acid-derived diamine (DFA diamine) or polyether diamine (PPO diamine) with five-membered tri(cyclic carbonate) by a pre-polymerization method. The obtained NIPUs were fur...
