  • Binder for manufacturing tufted floor coverings
    Patent number: 4370426
    Abstract: Aqueous latex base binder of a synthetic polymer for manufacturing tufted floor covering having improved wear-resistance. The content of hydrosoluble compounds dissolved in the aqueous phase in the latex is less than 0.5% by weight in relation to the polymer.
    Type: Grant
    Filed: August 15, 1980
    Date of Patent: January 25, 1983
    Assignee: Rhone-Poulenc Industries
    Inventors: Jean-Claude Daniel, Jacques Grossoleil, Robert Roullet
  • Binder for manufacturing nonwovens
    Patent number: 4360561
    Abstract: Aqueous latex base binder of a synthetic polymer for manufacturing nonwoven fabrics, and specifically webs for sanitary use having improved breaking strength. The content in the latex of hydrosoluble compounds dissolved in the aqueous phase is less than 0.5% by weight in relation to the polymer.
    Type: Grant
    Filed: July 30, 1980
    Date of Patent: November 23, 1982
    Assignee: Rhone-Poulenc Industries

  • Method of preparing homo and co-polymers of vinyl chloride adapted to give plastisols from a latex containing two populations of particles
    Patent number: 4340722
    Abstract: A method of preparing homo and co-polymers of vinyl chloride in the form of a powder adapted to give plastisols, in which a latex of homo or co-polymers of vinyl chloride, containing from 30 to 60% by weight of dry material and comprising two populations of particles with specific granulometric properties, is concentrated by eliminating a fraction of the aqueous phase in the liquid state, then the residual water is dried off. The dry material content of the concentrated latex is from 50 to 80% by weight, and the absolute difference between the dry material content of the latex before and after concentration is over 10% by weight.
    Type: Grant
