Abstract
Procedimiento para la purificación de propileno destinado a un procedimiento de polimerización en masa, en el que el polipropileno cristalino obtenido es separado de polímeros solubles y de componentes solubles del catalizador mediante extracción de la suspensión de polímeros procedentes del reactor de la polimerización, con un hidrocarburo líquido, caracterizado porque, antes de la extracción, la suspensión de polímeros se enfría hasta tal punto, que no tiene lugar ya una polimerización digna de mención, y porque la extracción se lleva a cabo sin adición de desactivadores, y el propileno que ha de ser purificado se agrega el líquido de la extracción.
