Process for drying and degassing of polyolefins and polyethylene manufactured by this process

The invention relates to a method for drying and degassing of polyolefins, which comprises contacting the a polymerization reactor leaving be polymerized with a degassing medium into contact with and is released simultaneously. As a degassing medium according to the invention is used, the monomer to be polymerized, flowing particularly in a circulation process by a depressurization vessel and preferably also with ethylene or other lower boiling olefin in an amount in the range of 0 to 100 mol%, based on the total amount of circulating gas, is enriched. according to the invention within the container Relaxing polymerization occurs in an amount of up to 10%, based on the total polymerization conversion.
