  • Process for the preparation of polymerized polyethylene wax
    Patent number: 11485806
    Abstract: The present invention relates to a process for the preparation of a polyethylene wax, the process comprising the steps of providing a catalyst solution, wherein the catalyst solution comprises at least one activating compound, an alkylaluminoxane and a me-tallocene complex, wherein the molar ratio of the activating compound to aluminum comprised in the alkylaluminoxane is from 0.0005 to 0.20; and polymerizing ethylene, by contacting the ethylene and the catalyst solution.
    Type: Grant
    Filed: November 6, 2017
    Date of Patent: November 1, 2022
    Assignee: SCG Chemicals Co., Ltd.
