Abstract
PURPOSE: A polymer produced by using a catalyst comprising a Ti component, an organoaluminum component and an organic acid ester is purified by bringing into contact with steam under specific conditions to lower the content of organic substances originated from the catalyst and remove the smell, thus permitting the use in food packaging.
CONSTITUTION: A powder of olefin polymer, which is produced by using a polymerization catalyst comprising a high-active titanium component supported on a magnesium compound, an organoaluminum compound such as triethyl aluminum and an organic acid ester boiling above 150°C such as methyl toluate and resultingly contains more than 5ppm of organic compounds originated from the organic acid ester, is placed in a vertical cylinder tank. The polymer is brought into contact with steam at a temperature lower than the melting point to reduce the content of the organic compounds in the polymer less than the half.
