FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing poly-alpha-olefin, which includes a step of polymerising at least one C8-C12-monomer, preferably decene, such as 1-decene, in the presence of aluminoxane, an activator an metallocene to obtain poly-alpha-olefin, where the molar ratio of aluminoxane to metallocene is less than 100:1. The poly-alpha-olefin has kinematic viscosity of less than 500 cSt at 100°C. The present invention also relates to a method of producing poly-alpha-olefin, having the desirable kinematic viscosity, from at least one monomer in the presence of aluminoxane, an organoboron compound and metallocene.
EFFECT: method is efficient for producing lubricant materials with good viscometric properties; it was also found that viscometric properties of the polymers can be finely adjusted by varying the molar ratios of the procatalyst, the cocatalyst and the activator.
