| titleOfInvention | METHODS FOR REGULATING VISCOSITY OF POLI-ALPHA-OLEFINS |
| abstract | 1. A method of producing a poly-alpha olefin, the method comprising the step of polymerizing at least one C-C monomer in the presence of alumoxane, activator and metallocene to produce poly-alpha olefin, wherein the molar ratio of alumoxane to metallocene is less than 250: 1.2. The method according to claim 1, where the molar ratio of alumoxane to metallocene is less than 100: 1.3. The method of producing a poly-alpha olefin according to claim 1, comprising the step of polymerizing at least one C-C monomer in the presence of an alkylaluminoxane, an organoboron compound and a metallocene to produce a poly-alpha olefin, wherein the molar ratio of aluminoxane to a combination of an organoboron compound and metallocene is less than 125: 1.4. The method according to claim 3, where the molar ratio of alumoxane to a combination of an organoboron compound and metallocene is less than 50: 1.5. The method according to any one of claims 1 to 4, wherein the poly-alpha olefin has a kinematic viscosity of less than 500 cSt at 100 ° C. The method according to any one of claims 1 to 4, wherein the metallocene is a compound of the formula (CpR) R (CpR) MX, where the Srligand (CpR) and Srligand (CpR) are the same or different cyclopentadienyl rings; each R and R are independently , hydrocarbyl, halocarbyl, heterocarbyl, an organic metalloid compound substituted with a hydrocarbyl, or a group of an organic metalloid compound substituted with a halocarbyl and containing up to 20 carbon atoms; m is an integer from 0 to 5; p is an integer from 0 to 5; two behind estitelya r and / or ROn adjacent carbon atoms of the cyclopentadienyl ring associated with it, can be connected together to form a ring fused |
