    Abstract: A polymer composition for producing gel extruded articles is described. The polymer composition contains polyethylene particles combined with a plasticizer and one or more surface tension reducing techniques. In one aspect, the surface tension reducing technique includes adding a filler or chemical component to the polyethylene polymer for increasing wettability. Alternatively, the surface tension reducing technique can be a surface treatment, such as a plasma treatment. Polymer articles made in accordance with the present disclosure can have dramatically increased wettability properties. In one embodiment, the polymer composition is used to form a porous membrane for use as a separator in electronic devices.

    Abstract: The present invention relates an emulsifier stabilized formulated copolymer dispersion, processes for forming the emulsifier stabilized formulated copolymer dispersion, and to uses thereof. The emulsifier stabilized formulated copolymer dispersion may be formed by polymerizing at least one monomer in the presence of a stabilizer package, to form an emulsifier stabilizer copolymer dispersion, and introducing a post-addition comprising a polyvinyl alcohol solution to the emulsifier stabilized copolymer dispersion to form an emulsifier stabilized formulated copolymer dispersion. The polyvinyl alcohol, added as solution, may be added in an amount from 1 to 10 % by weight, solid polyvinyl alcohol based on solids content of the emulsifier stabilized copolymer dispersion. The polyvinyl alcohol may have a molecular weight expressed as viscosity from 3 mPa·s to 60 mPa·s based on a 4 % solution at 20 °C and a degree of hydrolysis from 70 mol.% to 85 mol.%, preferably from 78 mol.% to 82 mol.%, more preferably 80 mol.%.

    Abstract: Ion chromatography may be used for measuring the concentration of metal ions in various streams of a vinyl acetate production process. For example, a method may comprise: reacting ethylene, oxygen, and acetic acid in the presence of a catalyst and optionally a catalyst promotor like sodium acetate and/or potassium acetate to yield a crude vinyl acetate stream; measuring a concentration of a metal ion of the crude vinyl acetate stream and/or a stream downstream thereof with an ion chromatograph, wherein the metal ion is selected from the group consisting of Group I metal ions, Group II metal ions, transition metal ions, and any combination thereof.

    Abstract: An artificial turf system is provided. The turf system comprises an artificial turf carpet comprising synthetic fibers and a plurality of infill granules disposed between the synthetic fibers. The infill granules have a curved shape and a length of about 5 millimeters or more. Further, the granules comprise a polymer composition that includes a polymer matrix, the polymer matrix including at least one thermoplastic elastomer.

    Abstract: Halogen-free, flame resistant polymer compositions are disclosed. The polymer composition contains a thermoplastic polymer, such as polybutylene terephthalate. The thermoplastic polymer is combined with a flame retardant that includes a phosphinate, a phosphite, and a nitrogen-containing synergist. In addition, the composition can contain a fluoropolymer and an organometallic compatabilizer. The flame resistant composition displays excellent flame resistance even when containing the thermoplastic polymer in amounts greater than 60% by weight.
