  • LINEAR LOW DENSITY POLYETHYLENES, POLYMERIZATIONS THEREOF, AND FILMS THEREOF
    Publication number: 20250206859
    Abstract: This disclosure relates to polyethylene polymers, polymerization processes for making such polyethylene polymers, and films made therefrom. In some embodiments, a polyethylene copolymer includes ethylene units; and 1 wt % to 8 wt % of Cs-Cs alpha-olefin comonomer units. The polyethylene copolymer has a density of 0.914 g/cm3 to 0.925 g/cm3 and a melt index (MI, determined per ASTM D1238 at 190° C. and 2.16 kg loading) greater than 1 g/10 min and less than or equal to 2.5 g/10 min. The polyethylene copolymer has a composition distribution breadth index of 75% or greater and a molecular weight distribution (Mw/Mn) of 2 to 8.

  • Preparing porous hydrogel products
    Patent number: 6511650
    Abstract: This invention is directed to a new approach to form porous hydrogel materials by first creating gas pockets in the gel and then removing this gas. The removal of the gas creates a porous material, and the initial incorporation of sufficient gas allows one to create a material with an open, interconnected pore structure. Advantageous features of the resulting materials, in addition to their interconnected pore structure, may include that the pore structure is maintained over extended time periods and that the gels maintain a high mechanical integrity that allows seeding with cells and implantation without destruction or compression of the material.
