The reactor consists of a reaction vessel, agitator and transmission system, cooling device, explosion-proof device, and heating furnace, etc. The polymerization reactor, also known as the esterification condensation reactor, is a reaction unit that completes esterification and condensation simultaneously. When performing esterification reactions in the esterification condensation reactor, water and low molecular weight substances produced during the esterification reaction are separated out through a rectification column, packed tower, and condenser. When performing condensation reactions in the esterification condensation reactor, the esterification valve is closed and the condensation valve is opened, the temperature is adjusted to a higher temperature, and through the agitator system, many similar or dissimilar low molecular weight substances interact to form high molecular weight substances, while also precipitating small fractions.

The offspring is collected and separated by the condenser receiver. The reactor for polymerization is widely used in organic synthesis, chemical fiber, and other fields.
