Abstract
A process for the separation of polyolefins manufactured at low pressure with the aid of catalysts. Carbon monoxide is added to the reaction mixture resulting from the polymerization. The process makes it possible to obtain perfectly homogeneous polyolefins which can be used for the manufacture of films and fibers.
