| Abstract: | It has been found that dimerization of ethylene ton-butenes proceeds selectively over Ni2+-Mont. Over Cr3+-Mont, extensive polymerization occurs and the polyethylene produced shows a high melting point and density. The catalytic activities for ethylene dimerization and polymerization are closely correlated with the acidity of catalysts. |
