摘要： An oligomer is made by contacting a straight-chain, .alpha.-olefinic monomer with boron trifluoride and a hydroxy carbonyl promoter. The hydroxy carbonyl is preferably a .beta.-hydroxy-ketone, such as 4-hydroxy-4-methyl-2-pentanone. A second promoter can be used in conjunction with the boron trifluoride and the hydroxy carbonyl promoter. Possible secondary promoters include aldehydes, alcohols, alcohol alkoxylates, carboxylic acids, ethers, ketones, and their mixtures. Preferably the oligomer product has a kinematic viscosity at 100.degree. C. of less than 1.7 cSt; has a dimer to trimer and higher oligomer ratio of at least 1:1; and is at least 90 wt. % dimer and trimer of the monomer.
