  • Large area orientation of block copolymer microdomains in thin films
    Patent number: 6893705
    Abstract: A method and apparatus for orientation of block copolymer microdomains via rapid solidification. Rapid solidification from a solvent may include directional solidification and/or epitaxy to form patterns of microdomains in a film of block copolymer. Microdomains may include various structures formed by components of a block copolymer, such as vertical lamellae, in-plane cylinders, and vertical cylinders, and may depend on film thickness. Orientation of structures in microdomains may be controlled to be approximately uniform, and spatial arrangement of microdomains may be controlled.
    Type: Grant
    Filed: May 28, 2002
    Date of Patent: May 17, 2005
    Assignee: Massachusetts Institute of Technology
    Inventors: Edwin L. Thomas, Claudio DeRosa, Cheolmin Park, Michael Fasolka, Bernard Lotz, Anne M. Mayes, Jongsesung Yoon

  • Semicrystalline manufactured articles made of syndiotactic poly-p-methylstyrene (s-PpMS)
    Patent number: 5468823
    Abstract: Semicrystalline manufactured articles made of syndiotactic poly-p-methylstyrene (s-PpMS) in a crystalline form having a high melting point (225.degree. C.), and processes for the preparation thereof. Processes for preparing semicrystalline manufactured articles (semi-finished products, formed articles, fibers, films, etc.) made of s-PpMS in its different crystalline forms by exposure of amorphous manufactured articles to suitable solvents and by subsequent thermomechanical treatments.
