Abstract

a presente invenção refere-se a um método para purificar um polímero recuperado, como um polímero recuperado de um uso pós-consumo ou uso pós-industrial. o método envolve a obtenção do polímero recuperado e do contato do mesmo em temperatura e pressão elevadas com um solvente fluido para produzir um polímero recuperado extraído. o polímero recuperado extraído é dissolvido em um solvente a uma temperatura e pressão elevadas para produzir uma solução de polímero, que é purificada a uma temperatura e pressão elevadas, mediante o contato da solução de polímero com um meio sólido para produzir uma solução de polímero mais pura. o polímero é, então, separado da solução de polímero mais pura.
