Abstract

The invention discloses a vacuum drum type polyester solid-phase polymerization device, which comprises a control cabinet, a vacuum pump, a bracket, a heating layer and a solid-phase polymerization kettle, and a first seal is installed on the feed pipe of the solid-phase polymerization kettle. A hollow shaft and an output shaft are respectively fixed in the middle of the two sides of the solid-phase polymerization kettle, and the solid-phase polymerization kettle is rotated and installed between two brackets through the hollow shaft and the output shaft, and the control cabinet is located on the side of the bracket. On one side, both sides of the control cabinet are equidistantly provided with heat dissipation ports, a buckle is fixed in the middle of the upper end surface of the control cabinet, and a motor is fixed inside the buckle, and the vacuum pump is located on a side of the bracket away from the control cabinet. On the side, the upper end of the vacuum pump is fixed with a suction pipe, and the end of the suction pipe away from the vacuum pump passes through the interior of the hollow shaft and is fixed in the solid-phase polymerization kettle. The invention has the advantages of reducing the difficulty of experiments, saving operation steps and being convenient for single-person experiment operation.

Description

technical field [0001] The invention relates to the technical field of solid phase polymerization, in particular to a vacuum drum type polyester solid phase polymerization device. Background technique [0002] Solid-state polymerization refers to the process in which the monomers that form polymers are polymerized in a solid state to form high molecular polymers. Solid phase polymerization is characterized by low activation energy of the polymerization reaction, no induction period, and obvious post-polymerization effects. The reaction mechanism of solid phase polymerization is free radical and ionic chain reaction polymerization mechanism, and polymerization can also be carried out by stepwise reaction. Generally, high-energy radiation or ultraviolet rays are used to initiate polymerization, and heat-induced polymerization is used. Solid state polymerization is limited to a small number of high melting point monomers. It is generally believed that the monomer molecules i...
