    Degradation of Polyesteramides during Composting under Standard and Isothermal Conditions

  • Original language description

    Polyesteramides based on e-caprolactam and e-caprolactone differing in content of ester/amide structural units were subjected to biodegradation ? composting in a big compost pile under controlled conditions (controlled composting) and in small compostersat steady temperature of 60 °C (isothermal composting). Both types of composting resulted in degradation of the polyesteramides depending on copolymer composition, isothermal composting being more robust. The contribution of abiotic hydrolysis to the degradation of polyesteramides was studied at 60°C in buffer solutions pH=5.4; 7.4 and 8.4. Experimental results gave evidence about prevailing effect of abiotic hydrolysis over biological one at 60°C. Ester bonds in polyestramide chains are cleaved preferentially, so the scope of degradation increases with the content of ester units in the copolymer.
