PROCESS FOR POLIMERIZATING PRODUCTION OF LINEAR POLIETHILEN WITH BIG STABILITY AND SMALL DENSITY |
摘要 |
A copolymer of ethylene and a higher alpha-olefin, preferably 1-hexene and/or 4-methyl-1-pentene, can be produced using an activated and subsequently carbon monoxide reduced chromium containing catalyst and a trialkyl boran cocatalyst. The polymerization process must be carefully controlled to produce a copolymer resin that can be made into a tough, impact resistant film. |
