Özet:

 

A series of degradable films was prepared, and 2 formulas of polyethylene  (PE) films with the highest degradable performance were experimentally  determined. These films contained 3.43% and 0.44% stearate, and were  denoted as PE-3 and PE-4, respectively. Their biodegradability was  studied in a laboratory-controlled composting test using ordinary PE film  (OPEF) as a control. Contrast composting experiments indicated that the  biodegradability of untreated samples was very low, and that the  biodegradation rates of PE films after natural aging were significantly  higher. FT-IR analysis showed that OPEF changed little after the composting  experiment, and that PE-3 and PE-4 showed a carbonyl absorption peak at  1720 cm-1, whose intensity increased with increased composting  time. Analysis of the viscometric-average molecular weight revealed that it  changed little for untreated film but significantly decreased for aged  films, especially PE-3, after the composting experiments.
