Abstract
A process is described for the production of a synthetic hydrocarbon especially useful as a base for high performance motor oils. The material is a oligomer of alpha-olefin monomer having a uniquely selective product distribution emphasizing tetramers and pentamers. This distribution is achieved through a controlled polymerization involving an initial oligomerization step followed by the delayed addition of fresh monomer to improve the yield of the desired tetramers and pentamers.
