The aim of this work was an estimation of susceptibility of biodegradable poly(ε-caprolactone) (PCL) to environmental degradation in different natural environments. The commercial poly(ε-caprolactone) film, the trade name “CAPA 680”, was degraded in the compost, pond, open and harbour area of the Baltic Sea. Characteristic parameters of all natural environments were monitored during the incubation of polymer samples and their influence on degradation of PCL was discussed. Susceptibility of PCL to degradation in natural environments was evaluated based on changes of weight, crystallinity and polymer surface morphology. The rate of environmental degradation of PCL depended on the incubation place, environmental conditions and decreased in order: compost>harbour area of the Baltic Sea>open area of the Baltic Sea>pond.
