Abstract
Method for obtaining biodegradable polyesteretheramide that has a stage of esterification and/or transesterification and amidation reaction, a stage of prepolycondensation, a stage of polycondensation, an optional stage of extraction, a stage of drying and a final stage of extrusion with additives. The method of obtaining PEEA enables better satisfaction of the needs of each client as regards viscosity, composition and additives. It enables reducing the amount of interface product that has lower commercial value and improves the colour of the product, while at the same time provides a more efficient process, ecologically cleaner and safer for all the operatives.
