Abstract
A synthetic oil is made by a process comprising the steps of (a) reacting a vinylidene olefin in the presence of a catalyst to form an intermediate mixture which contains at least about 50 weight percent dimer of said vinylidene olefin, and (b) adding a vinyl olefin to said intermediate mixture and reacting said intermediate mixture and said vinyl olefin in the presence of a catalyst so as to form a product mixture which contains said dimer of said vinylidene olefin and a codimer of said added vinyl olefin with said vinylidene olefin.
