    A one-step bulk polymerization procedure was used to prepare polyurethane (PUR) materials based on hexamethylene diisocyanate, 1,4-butanediol, and a macrodiol. Polycarbonate diol, polyoxypropylene diol, and polybutadiene diol were used as the macrodiols (MW ca 2000), with dibutyltin dilaurate as the catalyst. To evaluate the mechanical properties of the PUR materials, a common tensile test was performed at room temperature and dynamic mechanical analysis (DMA) in the temperature range of -100°C to +150°C. The effect of macrodiol type on mechanical behavior is discussed, together with the influence of the shape of the prepared materials (bulk, film) on the tested properties.
