  • High temperature syndiotactic styrene polymer foam
    Patent number: 6051621
    Abstract: Foamed polymeric materials exhibiting improved heat resistant properties and improved mechanical properties, as compared with known foamed styrene polymer materials, are obtained by expanding a polymer blend including a syndiotactic styrene polymer and an amount of an amorphous polymeric material which will impart enhanced heat resistant properties to the blend.
    Type: Grant
    Filed: January 7, 1999
    Date of Patent: April 18, 2000
    Assignee: The Dow Chemical Company
    Inventors: Kyung W. Suh, Creston D. Shmidt, Daniel D. Imeokparia, Alan E. Platt, Thomas E. Wessel
