  • Blends of &agr;-olefin/vinylidene aromatic monomer or hindered aliphatic vinylidene monomer interpolymers with polyolefins
    Patent number: 6388014
    Abstract: A latex or fiber comprising a blend of polymeric materials consisting of one or more &agr;-olefin/ vinylidene monomer non-crosslinked substantially random interpolymers, wherein the distribution of the monomers of said interpolymers can be described by the Bernoulli statistical model or by a first or second order Markovian statistical model, and one or more homopolymers or copolymers of monomer components comprising aliphatic &agr;-olefins having from 2 to 20 carbon atoms, or aliphatic &agr;-olefins having from 2 to 20 carbon atoms and containing polar groups.
    Type: Grant
    Filed: April 27, 2001
    Date of Patent: May 14, 2002
    Assignee: The Dow Chemical Company
    Inventors: Chung P. Park, Rene Broos, Johan Thoen, Martin J. Guest, Yunwa W. Cheung, John J. Gathers, Bharat I Chaudhary, Lawrence S. Hood
  • Blends of &agr;-olefin/vinylidene aromatic monomer or hindered aliphatic vinylidene interpolymers with polyolefins
    Patent number: 6329466
    Abstract: A foam comprising a blend of polymeric materials consisting of one or more &agr;-olefin/vinylidene monomer non-crosslinked substantially random interpolymers, wherein the distribution of the monomers of said interpolymers can be described by the Bernoulli statistical model or by a first or second order Markovian statistical model, and one or more homopolymers or copolymers of monomer components comprising aliphatic &agr;-olefins having from 2 to 20 carbon atoms, or aliphatic &agr;-olefins having from 2 to 20 carbon atoms and containing polar groups.
    Type: Grant

  • Blends of &agr;-olefin/vinylidene aromatic monomer or hindered aliphatic vinylidene monomer interpolymers with polyolefins
    Patent number: 6184294
    Abstract: A fabricated article other than a film comprising a thermoplastic blend prepared from polymeric materials consisting of; (A) from 1 to 99 weight percent of at least one interpolymer made from monomer components comprising (1) from 0.5 to 65 mole percent of (a) at least one aromatic vinylidene monomer, or (b) at least one hindered aliphatic or cycloaliphatic vinylidene monomer, or (c) a combination of at least one aromatic vinylidene monomer and at least one hindered aliphatic or cycloaliphatic vinylidene monomer, and (2) from 99.5 to 35 mole percent of at least one aliphatic &agr;-olefin having from 2 to 20 carbon atoms; and (B) from 99 to 1 weight percent of at least one polymer made from monomer components comprising at least one &agr;-olefin having from 2 to 20 carbon atoms. These articles possess improved properties when compared to the properties of articles derived from the individual polymers comprising the blend.
