摘要： Film having good blocking properties and low coefficient of friction is prepared without the presence of antiblock additives from certain thermoplastic ethylene interpolymer products. The thermoplastic ethylene interpolymer products have a density of about 0,935 g/ml or less, a melt flow ratio, I.sub.10/ I.sub.2, of at least about 8, and at least about 0.5 percent by weight of the interpolymer product has a weight average molecular weight of at least about 1,000,000 grams/mole. The interpolymer products are a blend or composite of ethylene polymers or copolymers and comprise at least a first interpolymer of ethylene with at least one alpha-olefin monomer. Preferably, the interpolymer products have a melt index, I.sub.2, of from about 0.1 to about 4 grams/10 minutes. The interpolymer products can be made using discrete polymer blends, or preferably, in a multiple reactor sequence. Blown film made from the interpolymer products is especially useful in grocery sack applications.

摘要： The present invention pertains to a continuous process and polymerization system characterized by separate injection of catalyst and make-up feed, an ethylene interpolymer composition characterized as having broad molecular weight distribution (MWD) and optimized compositional uniformity, a process for making such a composition and a fabricated article made from such composition. The novel composition is characterized as having a melt flow ratio, I10/I2, from 8 to 30, a Mw/Mn of greater than 4 as determined by gel permeation chromatography, a melt index, I2, from 0.01 to 1000 grams/10 minutes, preferably greater that 0.1 to 10 grams/10 minutes, and a density less than 0.945 g/cm3. The novel composition exhibits good processibility and improved toughness properties, especially excellent film tear and impact resistance, and is particularly well-suited for use in applications such as high performance trash can liners and heavy duty shipping bags.

摘要： Super high flow ethylene polymer compositions comprising at least one linear ethylene polymer are disclosed which have improved processability for use in making thermally formed articles (e.g., thin-walled lids, cups and containers). The compositions have a processing index from about 0.005 KPoise to about 1 KPoise and are particularly useful in thermal forming processes having shear rates of at least 2,000 sec.sup.-1 (e.g., injection molding processes). The compositions can be used to make thin-walled lids and cups and have good environmental stress crack resistance and Gullwing Tear properties.

摘要： The subject invention provides a polymer mixture having high heat resistivity, low hexane extractive and controllably lower or higher modulus. The mixture is comprised of at least one first substantially linear ethylene polymer, Component (A), and at least one second ethylene polymer which is a homogeneously branched polymer, heterogeneously branched linear polymer or a non-short chain branched linear polymer. When fabricated into film, the mixture is characterized by a heat seal initiation temperature which is substantially lower than its Vicat softening point as well as a high ultimate hot tack strength. When fabricated as a molded article, the mixture is characterized by high microwave warp distortion while maintaining a lower modulus. The polymer mixture is particularly well-suited for use in multilayer film structures as a sealant layer for such applications as cook-in packages, hot-fill packages, and barrier shrink films. In molding applications, the mixture is well-suited as freezer-to-microwave food storage containers and lids which maintain good flexibility at low temperature to allow easy openability of such containers.
