Abstract
A method for oligomerizing olefins in the presence of boron trifluoride and a co-catalyst comprising a heterogeneous cationic ion exchange resin catalyst is described. While the resin catalyst cannot oligomerize olefins by itself at temperatures around 75.degree.-85.degree. C., when used together with boron trifluoride an oligomer mixture may be created which has improved properties over oligomers made over only boron trifluoride. If a resin catalyst is used, a protonic promoter is not required.
