Synthesis and Characterization of Linseed oil Polyurethanes
Birten Çakmaklı
Polyurethane (PUR) plastic sheets (PLOH/PEG/HMDI and PLOH/PPG/HMDI) were prepared by reacting hydroxylated polymeric linseed oil (PLOH) synthesized from autoxidized linseed oil with diamine terminated polyethylene glycol (PEG) or diamine terminated polypropylene glycol (PPG) in the presence of hexamethylene diisocyanate (HMDI). These polyurethane and. PLOH was used to identify of chemical reactions by FTIR, H-NMR technique. These polyurethanes have different valuable properties, determined by their chemical composition. The effect of stoichiometric balance (i.e., PLOH/PEG/HMD and PLOH/PPG-2000/HMDI weight ratio) on the final properties was evaluated. The properties of the materials were measured by differential scanning calorimetry (DSC), thermo gravimetric analysis (TGA), and swelling rations.
