摘要: A copolymer of ethylene and a higher alpha-olefin, preferably 1-butane and/or 1-hexane, can be produced using an activated subsequently carbon monoxide reduced chromium containing catalyst system alkylaluminum or alkylboron cocatalyst. The polymerization process must carefully controlled to produce resin that made into tough product, with increased melt index broad molecular weight distribution.
