Abstract

Processes to prepare branched polyolefins for lubricant applications comprise combining at least one olefin and a coordination-insertion catalyst under conditions such that at least one oligomer product is formed. Low molecular weight by-products are fractionated out and the oligomer product is converted to a saturated hydrocarbon via hydrogenation.
