    <dct:description>&lt;p&gt;Aliphatic polyesters are the most promising biodegradable plastics because of their high susceptibility to the attack of hydrolytic&lt;br&gt; enzymes and of many microorganisms naturally occurring in the environment. Poly(butylene succinate-&lt;em&gt;co&lt;/em&gt;-adipate) (PBSA) is a biobased semicrystalline copolymer of poly(butylene succinate) (PBS), with adipic acid as co-monomer. It is highly biodegradable&lt;br&gt; because of its lower crystallinity and higher flexibility of polymer chains compared to PBS. In the present study, the&amp;nbsp;biodegradability mechanism of PBSA was evaluated using cutinase from &lt;em&gt;Humicola insolens&lt;/em&gt;, which is a commercial hydrolytic enzyme presenting both lipase and esterase features. The polyester&amp;nbsp;degradation is based on weight loss measurements&amp;nbsp;combined to other analyses (i.e., GPC, &lt;sup&gt;1&lt;/sup&gt;H NMR, and DSC) performed on the residual solids of PBSA&amp;nbsp;films, in order to understand the molecular and chemical modifications induced at the surface and/or in the bulk of polymer materials over time. The results showed that the enzymatic degradation mechanism of cutinase proceed&amp;nbsp;by degrading the polymer from the surface of the film. An exo-type cleaving action mode was proposed based on the identification of the oligomers and monomers released as degradation products.&lt;/p&gt;</dct:description>
