The estimation of degradibility of different polyurethanes under natural weather depending conditions in compost pile was the subject of the studies. The incubation of polymer samples took place for a period up to 24 months. The characteristic parameters of the compost: temperature, pH, moisture content, and activity of dehydrogenasis were monitored and their influence on degradation of polyuiretahnes was discussed. The compostability of PU was investigated by changes of weight, tensile strength, morphology, and thermal propeerties. In case of polyester-urethanes the crystallization as parallel to degradation, was evidenced.
