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.

Low molecular weight copolymer of ethylene and vinyl aromatic monomer and uses thereof

This invention relates to fabricated articles, including films or sheets prepared from blends of substantially random ethylene/propylene/vinyl aromatic monomer interpolymers with propylene homopolymers or copolymers. The fabricated articles exhibit high toughness, tensile properties and heat resistance and low stress whitening, and further can exhibit desirable optical properties, especially when in the form of a film or sheet.

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.

Process for making ultra-low molecular weight ethylene polymers and blends thereof

The present invention relates to a thermoplastic interpolymer product comprising an &agr;-olefin interpolymerized with at least one vinyl or vinylidene aromatic monomer and/or at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene aromatic monomer and, in at least one aspect, is characterized as having substantially synergistic thermal properties. The invention also relates to a process for manufacturing the interpolymer product wherein the process employs two or more single site or metallocene catalyst systems in at least one reaction environment and wherein at least two of the catalyst systems have (a) different monomer incorporation capabilities or reactivities and (b) the same or, optionally, different monomer sequencing and/or tacticity characteristics. With unique thermal property attributes, the interpolymer product is useful, for example, for impact, bitumen and asphalt modification, adhesives, dispersions or latexes and fabricated articles such as, but not limited to, foams, films, sheet, moldings, thermoforms, profiles and fibers.
