Abstract
Polímeros con unidades recurrentes de succinilo se obtienen segun un procedimiento mejorado mediante reaccion de A, un ácido dicarboxílico con 4 átomos de carbono insaturado o un derivado del mismo con B, un compuesto suministrador de nitrogeno, en una primera etapa de reaccion con obtencion de una mezcla de reaccion que contiene al menos un producto de reaccion de bajo peso molecular y a continuacion alimentacion en continuo de la mezcla de la reaccion en un reactor que trabaja en continuo con obtencion del polímero en una segunda etapa de reaccion.
