  • Compositions, processes for making, and articles of polyolefins, high density polyethylene and hydrocarbon resin
    Patent number: 6281290
    Abstract: Masterbatches comprising high density polyethylene (HDPE) are used for the production of polyolefin articles, particularly films. Employing HDPE in a masterbatch alone or in combination with a hydrocarbon resin and/or a polyolefin ultimately results in extruded polyolefin articles of optimal stiffness and ductility. Employing a high density polyethylene in combination with a hydrocarbon resin and a polyolefin in a masterbatch causes the masterbatch to solidify more rapidly and be pelletized more efficiently.
