Abstract
A biodegradable polyesteretheramide for manufacturing films and molded products, for example for application in the protection of foodstuff products and films for agriculture, contains a compound with at least 3 groups capable of reacting with one or several types of the active groups present in the reaction mixture, that is, compounds which, while containing ether groups in their structure, have active groups capable of reacting in the reaction mixture to form amide groups, and which simplifies and shortens the preparation process, reducing its economic cost and obtaining products of greater transparency and higher strain at failure, while maintaining other properties such as resistance to tearing and puncture, and allowing greater widths of films to be made with smaller thicknesses.
