Zeolite supported metal catalysts are prepared by ion exchange or incipient wetness impregnation, or by deposition of metal complexes, followed by calcination and reduction. Hydrogen reduction of encaged transition metal ions yields metal clusters or isolated atoms and protons of high Brlansted acid
Copolymerization of ethylene with higher a-olefins, such as 4-methyl-1-pentene, 1-hexene, 1-octene and 1-dodecene, was carried out with both aspecific and isospecific bridged metallocene complexes, comparing the catalytic behaviour ลฝ . following metallocene supportation on methylalumoxane-pretreated
