PROCESS FOR THE POLYMERIZATION OR COPOLYMERIZATION OF ETHYLENE |
摘要 |
In gas phase polymerizations and copolymerizations of ethylene, reagents or cofeeds control the molecular weight, expressed as MI (wherein MI is measured according to ASTM D-1238 Condition E), of the resin product. Use of isopentane and electron donating compounds reduce MI; whereas, water and electron withdrawing compounds increase MI.
