High viscosity polyalphaolefins

摘要

A synthetic lubricant material is produced by forming a catalyst complex of a boron trifluoride catalyst and at least one alcohol promoter in the absence of olefinic monomer, then oligomerizing a C4-16 olefinic monomer by adding the olefinic monomer to a reaction vessel containing the catalyst complex, under boron trifluoride pressure, to produce an oligomer product. At least 50 weight % of the olefinic monomer is C8-16 olefinic monomer.
