  • Patent number: 5573189
    Abstract: An extrudable composition formed of a blend of a polymer and a finely divided filler is prepared by combining the materials under conditions of high shear forces resulting in a composition which when diluted to a selected level has an application rate which is relatively higher than a composition having the same relative proportions of polymer and filler combined under conditions of low shear, the high shear forces reducing the aggregate size. The invention is also directed to a method for reducing the initial average aggregate size of a filler dispersed in a polymer by subjecting the mixture to high shear forces in a high intensity mixer.
