ABSTRACT:
A polymer forming assembly, for use in a reactor for carrying out a polymerization reaction, includes a casing mounted on the bottom of the reactor and formed with a polymer discharge channel communicating with the interior of the reactor, a block member secured to the bottom of the casing, and a cylindrical shaft member rotatably mounted in the block member. The cylindrical shaft is formed in its peripheral surface with an axially extending passage and a plurality of polymer outlets opposing and communicating with the passage. The polymer discharge channel in the casing is thus opened and closed by rotating the cylindrical shaft.
