Origin of High Segmental Mobility at Chain Ends of Polystyrene
Autor: Shigetaka Shimada, Osamu Urakawa, Yohei Miwa, Shogo Nobukawa
Publikováno v: Macromolecules. 43:7192-7199
Effects of solvents on segmental dynamics of polystyrene (PS) at the chain end have been studied by the site-specific spin-label method of electron spin resonance (ESR). PS’s having similar number-average molecular weight (ca. 25 kDa) but labeled w

An ESR Spin-Label Study on Molecular Mobility in the Interface between Microphases of a Diblock Copolymer: Effects of Admixture of Homopolymers That Are Miscible with One of the Blocks
Autor: Yohei Miwa, Katsuhiro Yamamoto, Masato Sakaguchi, Takuya Tanabe, Masahiro Sakai, Shigetaka Shimada, Shigeru Okamoto
Publikováno v: The Journal of Physical Chemistry B. 110:4073-4082
Molecular mobility in the interfacial region of a microphase-separated structure was studied in binary mixtures of AB-type diblock copolymers and homopolymers (miscible with only A) by the spin-label technique. In this study, we prepared (a) binary b
