Traditionally, polyurethanes (PU) are manufactured by reacting isocyanates with petroleum-based polyols (polyether or polyester). Because oil resources are diminishing and are becoming expensive to produce, engineers and scientist have discovered new technologies to fabricate plastics from renewable resources. The goal of this work was to determine mechanical properties of polyurethanes synthesized from castor oil and different isocyantes: isophorone diisocyanate IPDI, 1,6-diisocyanatohexane (HDI) and aliphatic polycyclotrimer (HDIt). The samples were prepared by a one-step reactive process with stoichiometric balance of reactive groups. The catalysed synthesis was performed at normal pressure. It was estimated that a mechanical properties of prepared samples were strongly influenced by the isocyanate type.
