  • Low molecular weight copolymer of ethylene and vinyl aromatic monomer and uses thereof
    Patent number: 7259219
    Abstract: An article of manufacture comprises a copolymer of ethylene and vinyl aromatic monomer having a molecular weight of less than 15,000. Preferably, the copolymer is characterized by a backbone having a first and second terminal end group, the first terminal end group is a methyl group, the second terminal end group is a vinyl group, wherein the ratio of the terminal methyl group to the terminal vinyl group is 0.8:1 to 1:0.8. The article of manufacture includes, but is not limited to, waxes, lubricants, additives, etc. The waxes may be used to formulate paints and coatings, printing inks, carbon paper, photo toners, building and construction materials, mold release agents, hot melt adhesives, candles. The waxes may also be used in wood processing, metal working, powder metallurgy and sintering, wax modeling, sizing, crop protection, and so on.

  • Process for making ultra-low molecular weight ethylene polymers and blends thereof
    Patent number: 6723810
    Abstract: Process for making a non-pourable ultra-low molecular weight ethylene polymer composition and blends thereof. Such polymer compositions tend to have longer lamella and a greater degree of crystalline organization than corresponding higher molecular weight materials at an equivalent density.
