Abstract

The work considers heat and mass transfer in the homophasic polymerization reactor. The reactor is a coaxial channel with internal tube in the form of a channel of confusor-diffuser type. The authors compared the degree of polymer transformation in the intensified coaxial reactor with internal tube of confusor-diffuser type and the reactor with constant rectilinear longitudinal section. It was found that in coaxial channels with internal tube of confusor-diffuser type, it is possible to reach high values of the transformation degree and to improve the quality of the obtained polymer.
