  Abstract

The biodegradable Properties of various polyester resins with different chemical structures have been studied by applying the controlled compost test and soil burial test. Celluose was taken as a fully biodegradable reference resin while PVC and PE were empolyed as non-biodegradable reference chains or ester group were rather easily degraded by hydrolase, meanwhile copolymer type polyesters which contain aromatic rings showed relatively low biodegradability. According to the results from controlled compost test, cellulose(the positive reference) showed 70.6% degradation after 45 days, whereas synthetic poly(butylene adipate-co-succinate), poly(butylene succinate), poly(butylene adipate-co-succinate-co-terephthalate) showed 44.0%, 32.0% and 23.4% degradation respectively. In this regard, it was concluded that biodegradable properties of polymers are largely dependant on the chemical structures constituting the polymers.
