    摘要: A grafted and/or functionalized macromolecule comprises entanglement-inhibited architecture wherein the polymer exhibits reduced melt viscosity. In one embodiment, the macromolecule comprises a polymer of an isoolefin having about 4 to about 7 carbon atom and a para-alkylstyrene, wherein a grafted macromonomer such as a terminally functionalized polystyryl chain of very narrow molecular weight distribution is attached to the para-alkyl group of the para-alkylstyrene such that entanglement of adjacent chains in the melt are inhibited. In addition to distributed macromonomer grafts, other functionality may be attached to the para-alkyl group of the para-alkylstyrene to introduce other desirable properties such as radiation curability. In another embodiment the macromolecule comprises a polymer of one or more simple olefinic monomers wherein a macromolecule is attached to pendent functionality and/or copolymerized into the polymer backbone. A particularly preferred macromonomer comprises a terminal norbornene functional group.

    摘要: Disclosed is a propylene impact copolymer comprising a first polypropylene having an MFR1 within the range from 15 to 40 dg/min; a second polypropylene having an MFR2 within the range from 50 to 190 dg/min; an elastomeric polymer; and wherein the propylene impact copolymer has an MFRICP within the range from 6 to 18 dg/min; a 1% Secant Flexural Modulus of greater than 150 kpsi (1030 MPa); and an Izod Impact at 25° C. of greater than 10 ft-lbs/in (530 J/m). The impact copolymer may be produced in a two or three tandem-reactor system wherein the catalyst composition used in the second reactor to produce the second polypropylene is different from the catalyst composition used in the first reactor to produce the first polypropylene.

    摘要: Plastic toughened plastics include a polymer composition having a polypropylene component and a second polymer component. The polypropylene component is present in an amount from about 50 to about 95 weight percent based on the total weight of the blend. The second polymer component is present in an amount from about 5 to about 50 weight percent based on the total weight of the blend, is a BOCD or BCD blend of at least two ssPE components, and has an overall density greater than about 0.90 g/cm3. Optionally, the plastic toughened plastics include one or more third polymer component selected from propylene-olefin elastomers and ethylene-propylene rubbers, which are present in an amount from about 1 to about 50 weight percent, based on the total weight of the blend.
