  • Publication number: 20200056018
    Abstract: Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.

    Abstract: A continuous solution polymerization process is disclosed wherein at least two catalyst formulations are employed. A first homogeneous catalyst formulation is employed in a first reactor to produce a first ethylene interpolymer and a first heterogeneous catalyst formulation is employed in a second reactor to produce a second ethylene interpolymer. Optionally a third ethylene interpolymer is formed in a third reactor. The resulting ethylene interpolymer products possess desirable properties in a variety of end use applications, for example in film applications. A means for increasing the molecular weight of the first ethylene interpolymer is disclosed and/or a means for increasing the temperature of the first reactor, relative to a third homogeneous catalyst formulation. A means for reducing the (?-olefin/ethylene) weight ratio in the first reactor is disclosed and/or reducing the density of the first ethylene interpolymer, relative to a third homogeneous catalyst formulation.

  • Publication number: 20200056028
    Abstract: The present invention is directed to a polyolefin composition which is suitable as sealing layer of a multilayer film providing improved, i.e. reduced sealing initiation temperature. The polyolefin composition comprises a random copolymer of propylene and a polymer of 1-butene. The present invention is also directed to oriented and non-oriented films comprising the polyolefin composition and to the use of a polymer of 1-butene in a polyolefin composition comprising a random copolymer of propylene for reducing the sealing initiation temperature of an oriented or non-oriented film comprising the polyolefin composition. The present invention allows the application of a random copolymer of propylene based polyolefin composition as sealing layer of a multilayer film for higher speed packaging lines and at the same time also provides good hot tack and optical properties.

  • Publication number: 20200056029
    Abstract: [Object] To provide a technology for imparting favorable slidability to fluorine rubber. [Solving Means] A composition for a sealing member includes: 100 parts by weight of an uncrosslinked fluorine rubber component; and 0.5 to 50 (inclusive) parts by weight of a particulate resin. The particulate resin includes a compatible portion and a lubrication portion, the compatible portion having compatibility with the fluorine rubber component, the lubrication portion having lubricity with respect to the fluorine rubber component. During molding of the composition for a sealing member, crosslinking of the fluorine rubber component progresses and at least a part of the particulate resin moves to a surface due to an action of the lubrication portion. As a result, a surface layer portion including a compatible portion and a lubrication portion is formed on a surface of a molded sealing member.
