Joshua B. Gaubert has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11680120
    Abstract: Embodiments of a method for producing a multimodal ethylene-based polymer having a first, second, and third ethylene-based component, wherein the multimodal ethylene based polymer results when ethylene monomer, at least one C3-C12 comonomer, solvent, and optionally hydrogen pass through a first solution, and subsequently, a second solution polymerization reactor. The first solution polymerization reactor or the second solution polymerization reactor receives both a first catalyst and a second catalyst, and a third catalyst passes through either the first or second solution polymerization reactors where the first and second catalysts are not already present. Each ethylene-based component is a polymerized reaction product of ethylene monomer and C3-C12 comonomer catalyzed by one of the three catalysts.

  • Publication number: 20220288906
    Abstract: Embodiments of the present disclosure are directed to multilayer films. Embodiments of the multilayer films may include a first layer comprising a polyethylene composition having a density of 0.924 g/cm3 to 0.936 g/cm3 and a melt index (I2) of 0.25 g/10 minutes to 2.0 g/10 minutes, a second layer comprising a first polyolefin, a third layer comprising a second polyolefin. The first layer may be positioned between the second layer and the third layer. The first polyolefin and the second polyolefin may be the same or different.

  • Publication number: 20220288899
    Abstract: Embodiments of the present disclosure are directed to multilayer films. Embodiments of the multilayer films may include a first layer comprising a first polyolefin, a second layer comprising a second polyolefin, a third layer comprising a third polyolefin, fourth layer comprising a fourth polyolefin, and a fifth layer comprising a fifth polyolefin. The second layer may be positioned between the first layer and the third layer; the third layer may be positioned between the second layer and the fourth layer; and the fourth layer may be positioned between the third layer and the fifth layer. Two or more of the first polyolefin, second polyolefin, third polyolefin, and fourth polyolefin may be the same or different. The third polyolefin may be a polyethylene composition having a density of 0.924 g/cm3 to 0.936 g/cm3 and a melt index (I2) of 0.25 g/10 minutes to 2.0 g/10 minutes.

  • Publication number: 20220275181
    Abstract: According to one or more embodiments, a polyethylene composition that is suitable for packaging applications may include a first polyethylene fraction and a second polyethylene fraction. The first polyethylene fraction may have a single peak in a temperature range of 45 C to 87 C in an elution profile via the improved comonomer composition distribution (iCCD) analysis method. The second polyethylene fraction may have a single peak in a temperature range of 95° C. to 120° C. in the elution profile via iCCD analysis. Additional embodiments disclosed herein include articles and films comprising the polyethylene compositions described herein.

  • Publication number: 20220056250
    Abstract: The present invention provides polyethylene-based compositions suitable for packaging applications, films, and articles. In one aspect, a polyethylene-based composition suitable for packaging applications comprises (a) at least 97% by weight, based on the total weight of the polyethylene-based composition, of a polyethylene composition comprising: (i) from 25 to 37 percent by weight of a first polyethylene fraction having a density in the range of 0.935 to 0.947 g/cm3 and a melt index (I2) of less than 0.1 g/10 minutes; and (ii) from 63 to 75 percent by weight of a second polyethylene fraction; and (b) 90 to 540 ppm, based on the total weight of the polyethylene-based composition of a calcium salt of 1,2-cyclohexanedicarboxylic acid; wherein the polyethylene composition has less than 0.10 branches per 1,000 carbon atoms when measured using 13C NMR, wherein the density of the polyethylene-based composition N is at least 0.965 g/cm3, and wherein the melt index (I2) of the polyethylene-based composition is 0.
