FIELD: chemistry.
SUBSTANCE: invention relates to a poly-alpha-olefin obtained from a decene and propene and having a branching level greater than 19% and to a method of producing such poly-alpha-olefins. The decene is 1-decene. Described is a method of producing a poly-alpha-olefin from at least two monomers, where two monomers include decene and propene. Polymerisation takes place in the presence of a metallocene catalyst Ph2C(Cp-9-Flu)ZrCl2 and an aluminoxane cocatalyst. Described also is a method which involves steps, among others, of providing correlation between the total amount of propene used to form poly-alpha-olefin and at least one of the characteristics of the poly-alpha-olefin: the branching level or viscosity of the poly-alpha-olefin.
EFFECT: producing poly-alpha-olefins containing decene and propene, with predictable levels of branching and viscosity.
