The invention discloses a macromolecular material
polymerization reaction kettle. The kettle comprises a kettle body, an upper closed cover, a drive sealing device, a stirring device, a feed and
discharge port, wherein the upper part of the kettle body is an inverted cone-shaped
wide mouth; the middle part of the kettle body is of a bucket shape; the lower part of the kettle body is cone; the kettle body is provided with a heating jacket 14 with a
spiral flow channel and a heat
insulation layer 9; the upper closed cover 6 is provided with a heating jacket 7, a heat
insulation layer 9, a vacuum port 8 and a feed port 12; the stirring device consists of a stirring shaft 5, an inner strip-shaped spiral stirring
paddle 3, an outer strip-shaped spiral stirring
paddle 2, a scraping blade 16 and a supporting oar 18; the drive sealing device consists of a motor, a
retarder and a sealing
machine; and the upper part of the stirring shaft is connected with the drive sealing device. The macromolecular material
polymerization reaction kettle has good stirring effect and
high heat and
mass transferring efficiency, can solve the difficult problems of pole climbing and devolatilization of high-
viscosity fusant and is in particular suitable for the
polymerization reaction of a high-
viscosity macromolecular material.
