| 摘要 |
The invention relates to a device for the synthesis of a polymer with extraction of a gaseous substance (8) comprising a reaction chamber (1) that comprises a substantially circular-cylindrical upper section (11), which is delimited by two circular faces (111, 112) and a lateral face (113) and has a cylinder longitudinal axis, and a lower section (12), an inlet opening (2), which is arranged in a circular face or the lateral face of the upper section (11), a first outlet opening (3), which is arranged in a wall of the lower section (12), a second outlet opening (4), which is arranged in the lateral face of the upper section (11) and lies opposite the first outlet opening (3), and a stripping apparatus (5), which is arranged such that the stripping apparatus (5) can rotate about the cylinder longitudinal axis and touches both circular faces and the lateral face. Said device can be used in particular for carrying out a method that comprises feeding an oligomer melt (6) into a reaction chamber (1) through an inlet opening (2), polymerising the oligomer melt (6) to form a polymer melt (7), removing the polymer melt (7) from the reaction chamber (1) through a first outlet opening (3) of the reaction chamber, and removing a gaseous substance (8) from the reaction chamber (1) through a second outlet opening (4) of the reaction chamber (1), wherein deposits on at least one inner wall of the reaction chamber (1) are removed by a stripping apparatus (5) and transported into the oligomer melt (6). |
