The object of the invention is to provide a polymerization processor from a raw material in a molten state, which can synthesize a polymer of high quality. Lactide sent from an apparatus for supplying lactide 1 is heated and molten in an apparatus for melting lactide 2 , and a catalyst is added to the lactide in an apparatus for supplying a catalyst 3 . The molten lactide is supplied through an apparatus for supplying lactide 4 to a horizontal reaction tank 5 , and flows by a head difference with a polymerization reaction proceeding. A discharged reaction solution is supplied to the upper part of a vertical reaction tank 6 , and flows through the vertical reaction tank 6 by gravity with the polymerization reaction proceeding. Thereafter, the reaction solution is transported to an apparatus for removing remaining lactide 7 , where unreacted lactide is removed, and then the reaction solution is discharged.
