ABSTRACT:
A high-temperature high-pressure process for producing an ethylene/.alpha.-olefin copolymer is provided in which a saturated hydrocarbon of 4 or less carbons is injected to an unreacted monomer mixture fed to a separator in a high-pressure recycling system. This process enables stable running of the production apparatus for a long term without clogging of the tubing in the high-pressure recycling system.
