Responsive sustainable and biodegradable systems based on Diels-Alder reaction from amylomaize starch

•New thermally responsive and sustainable systems were successfully obtained.•New architectures synthesized from starch and poly(butylene adipate-co-terephthalate).•Reversible networks based on reversible Diels-Alder reaction.•Systems developed to improve the incompatibility between starch and polyester.
