Filed: 1994-03-15
Abstract: PURPOSE:To obtain a polymer of a high quality in high productivity through prevention of the deposition/growth of polymer scale by locating the tip of a pipe for returning a condensate into a polymerizer to project into the vapor phase from the inner wall surface of the polymerizer. CONSTITUTION:In a polymerizer 1 equipped with a reflux condenser for heat removal and having a pipe 2 which is for returning a condensate formed in the condenser into the polymerizer 1, and is piped to a vapor phase section 5 in the polymerizer from the outside thereof, the tip 2a of the pipe 2 opening in the polymerizer 1 is located to project into the vapor phase section 5 from the inner wall surface 1a of the polymerizer. By using this equipment, the condensate flowing down from the reflux condenser does not come in direct contact with the inner wall of the polymerizer but falls down from the opening at the tip 2a as shown by an arrow 6, getting to the liquid surface 4a of the reaction mixture. Therefore, no polymer scale deposits and grows on the inner wall 1a, and then a polymer of a high quality with little fisheye can be produced with high productivity even in a long-term operation.
