Polymerizing An Ethylenic Monomer In The Presence Of A Preformed Sicp Or Solid Polymer And In The Presence Of A Nonreactive Material So As To Form An Aqueous Dispersion, Latex, Suspension, Or Emulsion Therewith; Or Product Thereof Patents (Class 524/457)
  • Patent number: 8993668
    Abstract: What are described are polyvinyl ester dispersions which are prepared in a multistage process and have a low content of polymerized acids or acid anhydrides. They can be obtained by a multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form are added to the reaction mixture in a second stage and then the polymerization is started again. The polymer dispersions obtained in this way are notable for a low coagulum content and for increased tensile strengths of the films formed therefrom.

  • Patent number: 8957134
    Abstract: A process for encapsulating pigment dispersions is provided where a pigment is dispersed with a polymeric dispersant in an aqueous solvent system. The free polymer dispersant in the pigment dispersion is limited to less than 0.12 grams per gram of pigment. This dispersed pigment is then encapsulated by adding acrylate monomers and optionally acrylic and vinyl monomers and polymerizing. In the encapsulated pigment dispersion the weight ratio of final free polymer to polymer found to the final encapsulated pigment is less than 0.9. The free polymer dispersant is measured by a centrifugation method and the final free polymer is measured by a density gradient centrifugation method. Such encapsulated pigment dispersions may be used in inkjet inks and are stable to heat, aging test conditions, and solvent challenges. Prints from these inks have better durability.

  • Patent number: 8394882
    Abstract: An improved process for emulsion polymerization of fluoropolymers, such as polytetrafluoroethylene, employs reduced amounts of fluorinated emulsifiers. The addition of europium III chloride facilitates emulsion polymerization of fluoropolymers having comparable quality to those fluoropolymers made using conventional processes employing greater amounts of environmentally undesirable fluorinated emulsifiers.

  • Patent number: 8324299
    Abstract: A moisture-curable hot-melt adhesive having an excellent balance of environmental friendliness, compatibility of ingredients, early-stage adhesive strength, heat resistance after moisture curing, tack free time, etc. and a method of manufacture for this hot-melt adhesive. A moisture-curable hot-melt adhesive which contains a urethane polymer that has a terminal isocyanate group and a moisture-curable hot-melt adhesive that contains urethane modified resin, has a residual percentage of isocyanate compound of 5 wt. % or less, and has a heat-resistant softening temperature after moisture curing of 60° C. or higher, has an excellent balance of the aforementioned. Urethane modified resin can be obtained by reacting a resin derivative that has a hydroxyl group with an isocyanate compound, and a moisture-curable hot-melt adhesive can be produced by mixing urethane-modified resin, polymer, and isocyanate compound.
