Effect of biodegradation conditions on morphology of ternary compositions of low density polyethylene with poly(lactic acid) and starch

Polyethylene–poly(lactic acid)–starch ternary compositions were obtained in a rotor disperser under conditions of shear deformation. Their biodegradation under the action of mold fungus spores and soil was investigated using IR spectroscopy and SEM. The changes under the fungal action revealed that the ternary blends represented a nutrient medium, while the exposure to soil led to alteration in morphology due to the whole range of numerous environmental factors.
