Abstract: Completely polymerizing olefinic monomer feed, in contact with a coordination catalyst suitable for olefin polymerization, in a mold having the shape of the article, at conditions under which the polymer is produced as a coherent, useful article in the shape of the interior of the mold, and removing the article from the mold.
