Abstract

Procedimiento para la eliminación continua de hidrocarburos residuales líquidos a partir de poliolefinas, que se habían obtenido en la polimerización catalítica de alfa-olefinas en presencia de mezclas catalizadoras en sí conocidas a base de compuestos de metales pesados y compuestos organometálicos, los hidrocarburos residuales siendo saturados con al menos 5 átomos de carbono en la molécula y siendo de aproximadamente 10- 50% en peso el contenido de hidrocarburos residuales en la poliolefina, por medio del vapor y agua.
