Abstract
Ethylene is oligomerized to linear, alpha-olefins by reacting ethylene in liquid phase solution in the presence of a catalyst composition produced by contacting in the presence of ethylene (1) a simple divalent nickel salt, (2) a boron hydride reducing agent, and (3) an o-dihydrocarbylphosphinophenyl alcohol or lower alkyl ether.
