Autor: Hidetoshi Ezure, Hiroaki Sata, Tsunehisa Kimura, Fumiko Kimura, Eiko Ito, Shintaro Tanaka

Publikováno v: Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals. 318:141-156

Magnetic orientation of poly(ethylene-2,6-naphthalate) (PEN) and isotactic polystyrene (iPS) has been reported. The orientation starts to occur during the induction period of isothermal melt crystallization process, i.e. during the initial stage of c

In situ FTIR spectroscopic study on crystallization process of isotactic polystyrene

Autor: Tsunehisa Kimura, Hidetoshi Ezure, Eiko Ito, Shintaro Tanaka

Publikováno v: Journal of Polymer Science Part B: Polymer Physics. 36:1227-1233

The melt crystallization process of isotactic polystyrene (i-PS) was studied by means of in situ Fourier transform infrared (FTIR) spectroscopy, with a focus on the conformational changes during the induction period. The spectra obtained during the i

Magnetic Orientation of Isotactic Polystyrene

Autor: Tsunehisa Kimura, Eiko Ito, Hidetoshi Ezure, Shintaro Ogawa

Publikováno v: Macromolecules. 30:3600-3605

Magnetic orientation of isotactic polystyrene during the isothermal crystallization at 210 °C in the magnetic field of 6 T is studied by using the magnetic birefringence, X-ray diffraction, and infrared measurements. The orientation starts in the vi
