The content of poly(ethylene glycol) in the composites ranged from 5 to 15 wt %. Differential scanning calorimetry study demonstrated that the melting temperature and the degree of crystallinity of polylactide decrease with increasing content of the oligomer additive. Analysis of the X-ray diffraction patterns of the composites confirmed the formation of a more amorphous phase. Optical microscopy revealed changes in surface morphology and structural order.

On the other hand, the focus on sustainable development in the field of ecology is stimulating interest in recycled polymers, whose use is seen as a solution to environmental problems. This study demonstrates that adding recycled polyethylene and biodegradable polymers, such as polylactide and polycaprolactone, to a low-density polyethylene matrix changes the morphology and properties of the blend, which makes it possible to improve the biodegradability of the material. It is shown that the presence of polycaprolactone and recycled polyethylene in the blend contributes to accelerated degradation of samples after 120 days of incubation in soil, with the appearance of biofouling and surface degradation observed. In a blend with polylactide, this effect is less pronounced, but a general change in properties and a decrease in weight are still present.
