Impact of bimodal pore MCM-41-supported zirconocene/dMMAO catalyst on copolymerization of ethylene/1-octene
The bimodal MCM-41-supported zirconocene/dMMAO catalyst exhibited higher catalytic activity for ethylene/1-octene copolymerization compared to the unimodal one. The higher activity can be attributed to lesser support interaction. The copolymer having broader MWD was obtained with the bimodal support without any significant changes in MW and polymer microstructure as seen by 13C NMR.
