  • Dispersible vinylidene chloride polymer powders as additives for polymers
    Patent number: 4575529
    Abstract: A vinylidene chloride polymer powder, having a second order transition temperature of at least about 50.degree. C., is recovered from a latex and dispersed with moderate shear in a non-solvent for vinylidene chloride polymers, such as a polyol used in the preparation of polyurethane materials. A dispersion of the powder and a polyol is eminently suitable for use in the preparation of polyurethane foams to impart enhanced flame retardancy and load-bearing properties thereto.
    Type: Grant
    Filed: October 19, 1981
    Date of Patent: March 11, 1986
    Assignee: The Dow Chemical Company
    Inventors: Dale S. Gibbs, Jack H. Benson, Reet T. Fernandez
  • Dispersible vinylidene chloride polymer microgel powders as additives for polymers
    Patent number: 4273901
    Abstract: A crosslinked vinylidene chloride polymer microgel powder is recovered from a latex and dispersed with moderate shear in a nonsolvent for vinylidene chloride polymers, such as a polyol used in the preparation of polyurethane materials. A dispersion of the powder and a polyol is eminently suited for use in the preparation of polyurethane foams to impart enhanced flame-retardancy and load-bearing properties thereto.
    Type: Grant
