Aliphatic polyesters which has flexible chain and ester bond are known likely degraded by hydroliase. From the test of controlled compost device, PBAS, PBS and PBAST showed 44.0%, 23.4% and 32.0% biodegradability respectively, while cellulose showed up to 70.6%. Mechanical property was also measured by UTM and observed decrement with the biodegradation of the materials. Biodegradability varied with the chemical structure of the polymer.
