  • Method of controlling kinematic viscosity of polyalphaolefin
    Patent number: 11370987
    Abstract: The invention relates to a method of the oligomerization of C6 and above olefin monomer whereby, at a fixed monomer/Al halide mole ratio, polyalphaolefins having desirable kinematic viscosities are prepared by controlling the oligomerization temperature. The oligomerization is carried out in presence of an oligomerizing catalyst comprising of aluminum halide and a promoter, and oligomerizing temperatures of about 10° C. to about 120° C.
    Type: Grant
    Filed: April 13, 2021
    Date of Patent: June 28, 2022
    Assignee: Indian Oil Corporation Limited
