C. Bergemann et al., COPOLYMERIZATION OF ETHYLENE AND LINEAR 1-OLEFINS WITH A METALLOCENE CATALYST SYSTEM UNDER HIGH-PRESSURE .1. COPOLYMERIZATION OF ETHYLENE AND PROPENE, Journal of molecular catalysis. A, Chemical, 102(1), 1995, pp. 1-5
The copolymerization of ethylene and propene under high-pressure and h
igh temperature was examined using a metallocene/methylaluminoxane cat
alyst system. The polymerization was performed in a continuously opera
ted stirred autoclave at 150 MPa and in the temperature range between
393 K and 493 K. The ratio of aluminium to catalyst metal used was 220
00 mol Al/mol Zr based upon a metallocene concentration of 6 x 10(-3)
mol-ppm in the feed. The reactivity ratios and the productivity as wel
l as the physical properties of the resulting polymers were determined
.
