    Inventors: Lloyd A. Goettler, Arthur J. Lambright
  • Method for treating discontinuous cellulose fibers characterized by specific polymer to plasticizer and polymer-plasticizer to fiber ratios, fibers thus treated and composites made from the treated fibers
    Patent number: 4414267
    Abstract: Discontinuous cellulose fibers are treated to improve their dispersability into a matrix comprising plasticized vinyl chloride polymer. The treatment includes contacting the fibers with a mixture of an aqueous dispersion of a vinyl chloride polymer and a plasticizer so as to coat the fibers, and drying the fibers. The non-aqueous portion of the mixture is usually present in an amount of at least 25 parts per 100 parts of fibers by weight, and the weight ratio of plasticizer to vinyl chloride polymer in the mixture is from 2:1 to 25:1. The discontinuous fibers thus treated can be dispersed into a matrix comprising plasticized vinyl chloride polymer with a minimum of mixing, and the improved composites thus produced contain a minimum of clumps of undispersed fibers.
    Type: Grant

    Assignee: Monsanto Company
    Inventors: Aubert Y. Coran, Lloyd A. Goettler
  • Treated fibers and bonded composites of cellulose fibers in vinyl chloride polymer characterized by an isocyanate bonding agent
    Patent number: 4376144
    Abstract: Cellulose fibers are treated with vinyl chloride polymer, a plasticizer and an isocyanate bonding agent. Composites are made from cellulose fibers dispersed in a matrix of plasticized vinyl chloride polymer, and bonded thereto with an isocyanate bonding agent. The composites can be molded or extruded to produce useful articles.
    Type: Grant
    Filed: April 8, 1981
    Date of Patent: March 8, 1983
    Assignee: Monsanto Company
    Inventor: Lloyd A. Goettler
  • Preparing a composite of wood pulp dispersed in a polymeric matrix
    Patent number: 4248743
    Abstract: A composite of polymeric matrix and wood pulp is prepared by masticating such proportion of polymeric matrix as provides a continuous phase and wood pulp having a tensile strength below about 10 kg/cm.sup.2. Water is added if needed to provide the requisite low tensile strength.
