  • Patent number: 10377840
    Abstract: Provided are novel ethylene acid copolymers, their ionomers and their use in various articles, including packaging films and injection molded articles. The ethylene acid copolymers comprise copolymerized units of ethylene, about 10 to about 30 wt % of copolymerized units of a first ?,?-unsaturated carboxylic acid having 3 to 10 carbon atoms; and about 5 to about 15 wt % of copolymerized units of a derivative of a second ?,?-unsaturated carboxylic acid having 3 to 10 carbon atoms. Preferred derivatives include esters, and in particular alkyl esters. These ethylene acid copolymers and ionomers have improved optical properties when compared to conventional ethylene acrylic or methacrylic acid copolymers and their ionomers.

  • Publication number: 20160236039
    Abstract: Disclosed is a golf ball comprising a cover prepared from an ionomer composition comprising a high acid ionomer comprising about 15 to about 30 weight % of copolymerized units of a C3-8 ?,?-ethylenically unsaturated carboxylic acid and about 3 to about 13 weight % of copolymerized units of vinyl acetate, alkyl acrylate or alkyl methacrylate.

  • Publication number: 20160167348
    Abstract: A multilayer polymeric sheet comprising three layers is provided. The two outer layers of the multilayer polymeric sheet comprise an ionomeric composition and are positioned on either side of the inner layer of the multilayer polymeric sheet, which comprises an ethylene vinyl acetate (EVA) composition. Further provided is a laminate comprising the multilayer polymeric sheet, for example, a glass laminate. Preferred laminates exhibit a sound transmission class of greater than 25, as measured by ASTM E314, or an effective stiffness by bending of about 3.0 mm to about 5.0 mm, as measured by ASTM C158. Also preferably, the laminate has an areal density that is lower than that of a glass monolith of comparable thickness.

  • Publication number: 20160076727
    Abstract: A lighting device comprising a light emitting diode and a cover comprising an ionomer composition that has improved optical properties. The ionomer composition comprises an ionomer that is produced by partially neutralizing a precursor acid copolymer that has a melt index of about 20 to about 400 g/10 min. The precursor acid copolymer comprises copolymerized units of an ?-olefin having 2 to 10 carbons and, based on the total weight of the precursor acid copolymer, about 12 to about 30 weight % of copolymerized units of an ?,?-ethylenically unsaturated carboxylic acid having 3 to 8 carbons.

  • Publication number: 20150158986
    Abstract: Provided herein are interlayer sheets formed of an acid copolymer composition, which comprises an acid copolymer resin or an ionomer that is the neutralized product of the acid copolymer resin. The acid copolymer resin comprises copolymerized units of an ?-olefin having 2 to 10 carbon atoms; about 10 to about 25 wt % of copolymerized units of a first ?,?-ethylenically unsaturated carboxylic acid having 3 to 10 carbon atoms; and about 15 to about 30 wt % of copolymerized units of a derivative of a second ?,?-ethylenically unsaturated carboxylic acid having 3 to 10 carbon atoms. In addition, the acid copolymer resin has a melt flow rate of about 1 to about 400 g/10 min. Light weight safety laminates comprising these interlayer sheets are characterized by good strength and superior acoustic damping, due to the properties of the acid copolymer composition.
