1. , the preparation method of the functional polyolefin resin of rare earth oxide participation, its step and condition are as follows:

  • (a) get 100 parts of polyolefin resin weight, and with its benchmark, get 0.05~

    5 part of peroxide initiator weight, 1~

    15 part of function monomer weight as other material weight umber proportioning;

    Correspondingly get 0.0010~

    0.0080 mole of rare earth oxide by per 100 gram polyolefin resines;

    Material by said ratio is joined in Henschel mixing tank, drum tumbler or the V-type mixing tank mechanically mixing 2~

    10 minutes, obtain pre-mixed resin;

    Described function monomer refers to a kind of in MALEIC ANHYDRIDE, vinylformic acid, methacrylic acid, methyl methacrylate and the glytidyl methacrylate or several;

    (b) pre-mixed resin that step (a) is obtained joins in the reactor, and temperature of reaction is 130~

    230 ℃

    , and the reaction times is 1.5~

    10 minutes, and polyolefin resin prepares functional polyolefin resin at molten state and function monomer generation graft copolymerization.
