Synthetic, biodegradable aliphatic polyesters often do not provide optimal properties of application (e.g. melting point of polycaprolactone: 60°C). Material properties of such polyesters can be improved by introducing aromatic compounds into polyme

Establishing carbon balances has been proven to be an applicable and powerful tool in testing biodegradability of polymers. In controlled degradation tests at a 4-L scale with the model polymer poly(β-hydroxybutyrate) (PHB), it was shown that the de
