Abstract
A process may include contacting an olefin monomer and a racemic bridged metallocene catalyst at a temperature of 80° C. to 150° C. in the presence of hydrogen. The racemic bridged metallocene catalyst may include a metallocene compound (A) and an activator component (B). The process may include recovering an effluent containing polyalpha-olefins (PAOs). The metallocene compound (A) may be represented by the formula R(Cp)(Cp)MXX. In the formula, R may be a C-Calkylene bridging group; Cpand Cpmay be the same or different substituted or unsubstituted tetrahydroindenyl rings; M may be a transition metal; and Xand Xmay be independently selected from hydrogen, halogen, hydride radicals, hydrocarbyl radicals, substituted hydrocarbyl radicals, halocarbyl radicals, substituted halocarbyl radicals, silylcarbyl radicals, substituted silylcarbyl radicals, germylcarbyl radicals, substituted germylcarbyl radicals.
