Description	The contribution addresses several problems associated with morphology of porous polyethylene and polypropylene particles produced in catalytic gas- and liquid-dispersion reactors. The knowledge of transport characteristics of monomers and diluents in polyolefin particles is important for the quantitative prediction of particle growth. Transport of monomers and diluents affects the rate of polymerization, the rate of particle growth, the copolymer composition distribution within the particle, and the morphology of growing particle. Moreover, transport characteristics have a strong impact on the course of degassing of polyolefin powder in the post-polymerization processing. Spatially three-dimensional morphology of porous polyolefin particles is digitally reconstructed from the X-ray micro-tomography images and stored in the form of binarized phase function. The methodology of this process is critically validated using (i) several types of samples ? porous polypropylene and polyethylene particles, poly The contribution addresses several problems associated with morphology of porous polyethylene and polypropylene particles produced in catalytic gas- and liquid-dispersion reactors.
