Abstract:<\/p>\n

The metal conaining additives based on chitosan polylactate (Chit-PLA) and Cu<\/em>2+<\/em>, Co<\/em>2+<\/em>, Zn<\/em>2+<\/em>\u00a0has been obtained. The influence of functional additives on the degradation of polyethylene was investigated. It was shown that the introduction of these additives in an amount of 0.5-5% into PE leads to increase of its strength to 28,7 \u2013 44,3 % and accelerates the destruction of the composites after UV exposure and natural factor of soil with pH 7,0\u20137,5. It was revealed that the presence of 0,5 % Chit-PLA-Zn<\/em>2+<\/em>\u00a0and 0,5 % Chit-PLA-Cu<\/em>2+<\/em>\u00a0in the composites resulted in the total loss of strength equals 17,2 <\/em>\u0438<\/em> 28,1 % after the action of soil microorganisms, equals 21,7 <\/em>\u0438<\/em> 18,7 % after UV exposure, respectively. The composition and intensity of the volatile products during degradation of the composites were characterized by pyrolysis mass spectrometry. The action of UV exposure and biological factors of soil causes the structural changes in the compositions with functional additives, that is fixed by the change of the decomposition temperature, the total intensity of the ion current, the number of ionic fragments, the temperature of maximal destruction.<\/em><\/p>\n
