摘要：
Abstract: Film materials based on low-density polyethylene (LDPE) containing 10–50 wt % of natural rubber (NR) and polylactide (PLA) subjected to ultraviolet radiation of various wavelength are studied. It is shown that natural rubber additives promote the degradation onset of the LDPE/NR material at a 254 nm wavelength, while no changes are observed in individual polyethylene. Analysis of the impact of 365 nm wavelength for 500 h on LDPE/PLA composites shows that the thermophysical characteristics worsen and the intensity of characteristic bands in the IR spectra changes significantly. © Pleiades Publishing, Ltd. 2024.
