Latest Patents
James L. Schulze holds a patent for gas phase polyethylene copolymers. This patent describes polyethylene copolymers with a structure that provides improved film properties. The copolymers can have a density ranging from about 0.905 to about 0.911 g/cm. Additionally, they can exhibit a DRI/I2 ratio of about 0.0008 to about 0.060, an I2 value of about 0.6 to about 3.8 dg/min, and an I21 value of about 8 to about 57 dg/min. The copolymers are produced by introducing ethylene and at least one other olefin comonomer to a single reactor at a comonomer/ethylene mole ratio of about 0.02 to about 0.03. The polymerization occurs at a temperature of about 76.7°C to about 80.6°C and a pressure of about 1,724 kPa to about 2,413 kPa. These copolymers can be utilized to create films with a 21 mol % Otransmission rate of about 150 to about 200 cc/100 in/24 hr and hot tack seal initiation temperatures of about 65°C to 80°C.
