REACTOR AND PROCESS FOR SOLID PHASE CONTINUOUS POLYMERISATION OF POLYETHYLENE TEREPHTHALATE

Application 978/KOLNP/2005 published 2006-09-15, filed 2005-05-25
A reactor and a process for solid phase continuous polymerisation of polyethylene terephthalate (PET) in order to achieve an increase of the intrinsic viscosity (I.V.) of a low molecular weight PET pre-polymers flow, wherein the formation of a plurality of fluidised stages in series (109; 309) is provided, being said PET pre-polymers flow fed into said fluidised stages in series (109; 309) and being an inert gas flow fed either in cross-flow or in counter-current flow with respect to said PET pre-polymers flow. (FIG.1)
