Abstract
A process for producing stabilized polyolefins comprising adding an epoxide to a polyolefin slurry obtained through polymerization of .alpha.-olefins in the presence of a catalyst containing a halide of a transition metal and an organoaluminum compound to render the catalyst remaining in the polymer inactive, and then subjecting the polyolefin slurry after the above inactivation treatment to an evaporation treatment. The process is extremely simple and results in polyolefins and molded products which are highly stable against discoloration and heat.
