1. method for preparing matrix material, this method comprises the steps:

  • (a) hydrophilic clay is dispersed in the water, so that the clay swelling;

    (b) from the swollen clay, remove and anhydrate, make organophilic clay;

    (c) to organophilic clay be inert solvent and alkylaluminoxane in the presence of, organophilic clay is contacted, to form clay/alkylaluminoxane mixture with alkylaluminoxane;

    (d) this mixture is contacted with the catalyzer that can promote olefinic polymerization, to form clay/alkylaluminoxane/catalyst complex;

    With(e) mixture of step (d) is contacted with olefinic monomer, form matrix material.
