  • Fibers made from long chain branched syndiotactic vinyl aromatic polymers
    Patent number: 6037048
    Abstract: Fibers having increased strength and small diameters can be produced from compositions comprising long chain branched syndiotactic vinyl aromatic polymers. Due to the increased fiber strength, less strand breakage occurs during processing which increases process productivity and yield.
    Type: Grant
    Filed: June 29, 1999
    Date of Patent: March 14, 2000
    Assignee: The Dow Chemical Company
    Inventors: Curtis E. Peterson, Roel H. Vossen, Yi-Bin Huang, Paul J. Moses, Jr.
  • Fibers made from long chain branched syndiotactic vinyl aromatic polymers
    Patent number: 5965682
    Abstract: Fibers having increased strength and small diameters can be produced from compositions comprising long chain branched syndiotactic vinyl aromatic polymers derived from the polymerization of a vinyl aromatic monomer in the presence of from 10 to 1000 ppm, based on the amount of vinyl aromatic monomer, of a multifunctional monomer having more than one olefinic functionality. Due to the increased fiber strength, less strand breakage occurs during processing which increases process productivity and yield.
