Abstract

UN PROCESO PARA EL ENRIQUECIMIENTO DEL ESTADO SOLIDO DE UNA RESINA DE POLIESTER MEDIANTE LA REACCION DE POLIADICION EN LA QUE LA RESINA SE ENRIQUECE EN PRESENCIA DE UN ADITIVO DE ENRIQUECIMIENTO QUE ES UN COMPUESTO DISTINTO A UN DIANHIDRO DE UN ACIDO TETRACARBOXILICO AROMATICO, QUE CONTIENE DOS GRUPOS CAPACES DE REACCIONES DE ADICION CON LOS GRUPOS TERMINALES DEL POLIESTER, SELECCIONADOS POR EJEMPLO EN EL GRUPO DE LOS DIANHIDROS DE LOS ACIDOS TETRACARBOXILICOS ALIFATICOS Y CICLOALIFATICOS.
