Abstract
Gas transport and physico-mechanical properties of synthesized films based on modified starch and chitosan have been studied. The values of the permeability coefficients of pure gases included in the air for films based on modified chitosan and a copolymer based on modified starch and chitosan at a temperature of 23°C were determined. The oxygen permeability coefficient of the synthesized copolymer was compared with other polymers. A copolymer based on modified starch and chitosan was found to have medium oxygen barrier properties. The biodegradability of the samples under the action of the micromycete Aspergillus niger was studied by analyzing the degradation products by chromatography-mass spectrometry. The total biodegradation time of the samples was 4 weeks. These films are promising for use as packaging material.
