摘要： Continuous polymerization method using a tubular continuous polymerization apparatus, wherein a peg 1 for tube cleaning is passed through a polymerization solution in polymerization tube 6 while contacting with the inner wall of the tube during the polymerization. The apparatus used in the method is equipped with polymerization tube 6; a first raw material inlet tube 8 connected with polymerization tube 6; a peg inlet tube 4 connected with polymerization tube 6; a second raw material inlet tube 10 connecting tube 8 with tube 4; valve 5 for opening and shutting between polymerization tube 6 and tube 8; valve 3 for opening and shutting between tube 10 and tube 4; and valve 7 for opening and shutting a connection between the tube 8 and tube 10. The invention can (1) eliminate the washing and cleaning of the polymerization tube at the exchange of species; (2) reduce loss in raw material and time which goes on until the inside of the tube reaches a steady state and (3) prevent scale production on the inner wall of the polymerization tube.
