  • Process for the manufacture of linear polyethylene containing .alpha.-alkene commonomers
    Patent number: 5236998
    Abstract: A process for making a blend of high-density polyethylene polymers containing one or more C3 to C12 .alpha.-olefin comonomers. The process begins in two parallel streams. In one stream ethylene is polymerized alone, and in the second stream ethylene is polymerized with the comonomer(s). The two streams are combined in a subsequent reactor where the polymerization process is completed. The polymerization produces a polymer wherein the comonomer is concentrated in the higher molecular weight fractions.
