    Abstract: The present invention provides an ethylene/glycidyl acrylate copolymer aqueous dispersion composition ensuring an obtained film (e.g., coating film) with excellent adhesion, and high stability of the film itself.
    Specifically, the present invention provides an ethylene/glycidyl acrylate copolymer aqueous dispersion composition, comprising:

    (A) an ethylene/glycidyl acrylate copolymer,
    (B1) an ethylene oxide/propylene oxide copolymer,
    (B2) a polyoxyalkylene-based non-ionic surfactant,
    (C) an alkali-soluble acrylic resin emulsion, and
    (D) a basic substance,
    wherein (B1) and (B2) are present in a total amount of 5 to 15 parts by mass, and (C) is present in an amount of 0.1 to 50 parts by mass per 100 parts by mass of (A), and
    (D) is present in an amount of 0.01 to 0.2 parts by mass per part by mass of (C).

    Abstract: The present invention relates to tackifier compounds and methods of using the same. In various embodiments, the present invention provides a tackifier compound including independently substituted or unsubstituted fused rings A and B each independently chosen from (C5-C10)cycloalkyl and (C2-C10)heterocyclyl. Fused ring A is substituted with (R1)1-8 and fused ring B is substituted with —(OC(O)R′C(O)R2)1-8. At each occurrence R′ is independently chosen from (C2-C10)alkanylene, (C2-C10)alkenylene, (C2-C10)alkynylene, (C5-C20(arylene), and (C1-C20)heteroarylene, wherein R′ is unsubstituted or substituted. At each occurrence R′ is independently selected from —OH, —OR3, and —OC(O)R′C(O)R2. At each occurrence R2 is independently chosen from —OH, —OR3, —NH2, —NHR3, and —NR32. At each occurrence R3 is independently chosen from (C1-C10)alkanyl, (C2-C10)alkenyl, (C2-C10)alkynyl, C5-C20(aryl), and (C1-C20)heteroaryl, wherein R3 is unsubstituted or substituted.

    Abstract: Blended fluoropolymer compositions are provided. In one embodiment, a liquid dispersion of a first fluoropolymer is blended with a liquid dispersion of a second fluoropolymer. The first fluoropolymer may be polytetrafluoroethylene (PTFE), such as a low molecular weight PTFE (LPTFE) that has been polymerized via a dispersion or emulsion polymerization process, and which has not been agglomerated, irradiated, or thermally degraded. The LPTFE may be in the form of an aqueous dispersion, having a mean particle size of less than 1.0 microns (□m), with the LPTFE having a first melt temperature (Tm) of 332° C. or less. The second fluoropolymer may be a melt processable fluoropolymer (MPF), such as methylfluoroalkoxy (MFA), fluorinated ethylene propylene (FEP), or perfluoroalkoxy (PFA), for example, in the form of an aqueous dispersion, and having a mean particle size of less than 1.0 microns (□m). Blending of the dispersions facilitates interaction of the LPTFE and MPF on a submicron level to facilitate intimate blending such that, when the blended fluoropolymer composition is dried, a crystal structure representing a true alloy of the fluoropolymers is formed, having melt characteristics that differ from those of the individual fluoropolymers. The blended fluoropolymer composition may be used to provide a coating having improved impermeability, stain resistance, abrasion resistance, smoothness, and higher contact angles.
