“…Thus, a number of studies deal with the mechanisms and kinetics of degradation as well as stabilisation of these polymers. [1][2][3][4][5][6][7][8][9][10] Recently, a new ecological problem connected with utilisation of plastic waste, appears. Most plastics based on polyolefins degrade very slowly under environmental conditions.…”

ABSTRACT:Commercial polyethylene (LDPE) was physically modified by low-molecular organic compounds for acceleration of photodegradation. Two ketones (acetophenone, benzophenone) and two aromatic chloro-derivatives (benzyl chloride and 1-chloromethyl naphthalene) in the same amounts (1%wt) were used for PE modification. The influence of UV irradiation on thin films of doped PE was studied using Fourier transform infrared (FT-IR) and UV-vis spectroscopy. Much higher yields of photoprocesses in polyethylene (PE) containing modifiers were confirmed. Effectiveness of modifier depends on chemical structure and absorption of incident UV-radiation. The possibility of obtaining of degradable packaging films based on modified PE is suggested.
