Abstract

a presente invenção refere-se a um método para purificar polipropileno recuperado, como um polipropileno recuperado de pós-consumo ou pós-indústria. o método envolve obter o polipropileno recuperado e colocar o mesmo, sob temperatura e pressão elevadas, em contato com um solvente fluido para produzir um polipropileno recuperado extraído. o polipropileno recuperado extraído é dissolvido em um solvente sob temperatura e pressão elevadas para produzir uma solução de polipropileno, a qual é purificada sob temperatura e pressão elevadas mediante o contato da solução de polipropileno com um meio sólido para produzir uma solução de polipropileno mais puro. um polipropileno mais puro é, então, separado da solução de polipropileno mais puro.
