Polyesteramides based on epsilon-caprolactam and epsilon-caprolactone differing in the content of ester-amide structural units were subjected to biodegradation - composting in a big compost pile under controlled conditions (controlled composting) and in small composters at a steady temperature of 60 degrees 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 degrees C in buffer solutions with pH 5.

Two types of copolymers--poly(ester-amide)s--by the anionic copolymerization of epsilon-caprolactam and epsilon-caprolactone, and aromatic-aliphatic copolyesters based on glycolyzed polyethylene terephthalate from used beverage bottles and epsilon-caprolactone were prepared. Biodegradation tests of these copolymers were performed by two methods, viz. composting under controlled conditions and treatment with ligninolytic fungi.
