El objetivo de este trabajo es promover la recirculación de residuos de poliéster como el polietileno tereftalato (PET) para envases en mezcla con poliolefinas (POs). Se propuso estudiar y conocer la interacción del material a recircular con dos diferentes compatibilizantes, los cuales se emplearon de manera individual y combinada. Los agentes compatibilizantes consistieron principalmente en copolímeros con funcionalidad epóxica y anhídrido maleico. Mediante análisis con calorimetría diferencial de barrido (DSC) e índice de fluidez (MFI) se demostró la interacción de los agentes de acople y el material para reciclado de PET / POs, relacionando el comportamiento de fusión, cristalización y la capacidad para fluir del material reciclado.
