VALIDATION OF MATHEMATICAL MODEL FOR TRANSPORT AND REACTION IN POROUS POLYOLEFIN PARTICLES
Original language description
Transport of monomers and diluents in porous polyolefin particles growing in gas- and liquid-dispersion reactors affects not only rate of polymerization and rate of particle growth, but also several important properties of the produced particle, such ascopolymer composition distribution within the particle and the particle morphology. Furthermore, transport characteristics of polyolefin particles have a strong impact on the degassing of polymer powder in the down-stream processing. This contribution can be divided into two parts. First, the methodology of digital reconstruction of spatially 3D polyolefin particle morphology using X-ray tomography images is presented. Advantages as well as problems and limits associated with the X-ray micro-tomographyimaging of polymer samples are critically examined. Second half of the report describes the mathematical model of transport and reaction in porous polyolefin particles with real structure. Because of complex morphology of polyolefin parti
