Abstract

Patente de Invenção "PROCESSO DE PRODUçãO DE COPOLìMERO DE POLIPROPILENO". Processo de dois estágios em fase gasosa para a produção de copolímeros de polipropileno, tendo um bom equilíbrio de resistência ao impacto e rigidez. A coesão do polímero, a incrustação e a produção de géis no segundo reator são reduzidas pela adição a um material substancialmente gasoso, passando através do circuito de reciclo do primeiro estágio do primeiro reator, de uma proporção de pelo menos um componente de redução.
