dc.description.abstractFoils from oxo-degradable polypropylene and poly(lactic acid) in various ratios were prepared, using a single screw extruder and a three-roll calender. The samples of the blend were subjected to aging in natural conditions and to biodegradation in composting conditions. The intensity of biodegradation of the various components was investigated through the change in tensile strength and elongation at break, as well as through Fourier transform infrared spectroscopy. It was established that the blends obtained from both polymers degraded in composting conditions, and it was possible to control the polylactide degradation and to obtain the required properties of the final products by varying the polypropylene content in the blend.
