AbstractThis is an experimental study on behaviour of oxo-biodegradable plastics containing additives during service life. Low density polyethylene is a most extensive used synthetic polymer with the largest production, because an important part of the production is converted into various products with short life cycle. The goal of this paper was to quantify the biodegradation of two low density polyethylene films containing 10% and 20% pro-oxidant AddiFlex in soil columns. Previously, the physical-mechanical properties and heavy metal content in polymer films have been determined. The obtained degree of mineralization was around 60% after 200 days of incubation for both studied polymer films (59.8% for 10% additive and 64.3% for 20% additive).

AbstractA metallocene catalysed linear low density polyethylene (mLLDPE) was mixed with very low amounts of bitumen (1-2%) as an additive. Bitumen interacts with mLLDPE giving rise to a dying effect, which turns the originally white mLLDPE extrudates into black. No slippage is observed during extrusion and sharkskin is postponed as bitumen is added. “Melt strength” values of the blends, determined in melt spinning experiments, are very similar to those of mLLDPE. Accordingly good performance is expected in film-blowing process. Tensile modulus values are higher than 109 Pa. Bitumen emerges as an alternative to carbon black powder currently used to obtain black polymer films.
