Interfacial polycondensation of polyarylate in Taylor-Couette-Reactor
چکیده انگلیسی

The interfacial polycondensation of polyarylate in Taylor-Couette-Reactor has been investigated. The influence of the following parameters: initial mole ratio of monomers, intensity of mixing, volumetric mixture flow rate, annular gap width and temperature on properties of polymer (average molecular weight and polydispersity index) were examined. The possibility of obtaining a product displaying desirable properties suitable for the production of fibres or polymeric films has been shown. The desired properties of polymer can be obtained for the following ranges of the process parameters: 0.7 < M0 < 0.9 and 1210 ≤ Rerot ≤ 1400 for T = 20 °C, τ = 60 s and η = 0.93. Considerably shorter residence times, of the order τ = 60 s, have been reached in Taylor-Couette-Reactor in comparison with reaction times in the Stirred-Tank-Reactor, of the order t = 300–600 s.
