The mechanical stability of biocatalyst particles in bioreactors is of crucial importance for applications of immobilized-cell technology in bioconversions. The common methods for evaluation of the strength of polymer beads (mostly force-to-fracture or tensile tests) are, however, not yet proven to
## Abstract **Summary:** The effective immobilization and activation of a singleβsite chromium catalyst for ethylene polymerization has been achieved using MgCl~2~/AlR~__n__~(OEt)~3βββ__n__~ supports, without the use of methylaluminoxane (MAO) or a borate activator. High catalyst activity and a sph
