摘要： A novel polymer and process for producing polymers incorporating linear long chain side branches are provided. The long chain linear branches occur at a frequency of less than 5.0 branches per 1000 carbon atom of the main polymer chains with at least some branches having a molecular weight greater than the critical molecular weight for entanglement of the polymer. The linear long chain branched polymers are produced by alpha-olefin macromolecule incorporation during bridged metallocene catalyst polymerization in solution and slurry processes. The polymers are characterized by superior processability characteristics of the polymer melts and superior mechanical characteristics of the solid polymers. The polymers are useful for fabrication into a wide variety of articles by conventional fabrication techniques.

摘要： This invention relates to polypropylene blends, particularly blends of high molecular weight amorphous polypropylene with lower molecular weight isotactic polypropylene. These blends exhibit unusual elastomeric properties. This invention also relates to the production of polypropylene blend compositions using at least two catalyst systems, one for producing amorphous polypropylene and one for producing crystalline polypropylene.

摘要： A process for the production of block copolymers of ethylene and an α-olefin such as propylene by using an ionic catalyst system including a metallocene component and a component having a cation capable of donating a proton and a compatible non-coordinating anion. Novel block copolymers are produced.
