Original Abstract
New elastomeric bio-polyol based polyurethanes (PUs) with specific mechanical properties were prepared by one-shot process. Commercial non-degradable polyether polyol derived from petrochemical feed stocks was partly substituted by the biodegradable polyhydroxybutyrate (PHB). An analysis by SEM proves that prepared materials have character of particle reinforced composite material where PHB particles are regular with size of about 1 – 2 micrometer in diameter. Tensile measurement demonstrates that Youngs modulus of each sample increase with increasing volume fraction of the filler.
