Polymerization process

摘要

Polymerization of a mono- alpha -olefine monomer is effected by contacting the gaseous monomer with a solid phase comprising polymer and catalyst at a pressure and temperature which are such that the temperature is in the range from tp + 0.1 DEG C up to tp + 5.0 DEG C, where tp is the temperature at which the monomer condenses at a pressure which is equal to the monomer partial pressure within the polymerization vessel.
