  • Patent number: 5095058
    Abstract: Aqueous dispersions of polyamide resins having improved stability with respect to gelation and phase separation are provided, along with preparative methods therefor. The improved stability of the provided aqueous dispersions is achieved by the addition to such dispersion of a chemical moiety, such as a water soluble, amphoteric amino acid, anionic and cationic salts of amino acid, or mixtures thereof, in aqueous solutions. In a preferred embodiment, a dispersion-stabilizing amount of glycine is added with the inversion water used to invert an emulsion of water in polyamide resin. The resulting emulsion of resin in water is then cooled below the resin's melting point, causing the emulsified droplets of the polyamide resin to solidify as finely divided particles which are dispersed uniformly through the aqueous phase. The stable, aqueous dispersions of this invention are useful in coatings, inks, and as coatings for hot melt adhesive applications.

  • Patent number: 4808642
    Abstract: This invention relates to a chlorine-containing resin molding characterized by its stabilization by aminocarboxylic acid and from which molding substantially no metallic ion is detected, and to material for use with the chlorine-containing resin molding consisting of 100 parts by weight of chlorine-containing resin and 0.5-5.0 parts by weight of aminocarbolyxic acid. According to the molding and the material for use therewith, there is no possibility of metallic ion dissolving from the molding in which a metallic stabilizer is conventionally used, with the result that the molding finds wide application in the industrial field related with electric parts including a semiconductor as a main item, medical treatment, chemicals and pharmaceuticals, and food stuffs, all subject to adverse effects by dissolution of metallic ion. Consideration for application of a nonmetallic agent is also given to the use of a coloring agent and a lubricant with respect to the molding and the material for use therewith.
