内山 昭彦 Akihiko UCHIYAMA |
| ＜要旨＞ This
article presents our two novel polymer technologies on retardation films
(RF). One is the wide-band RF that consists of molecular designed polymer
based on our birefringence dispersion control theory. The other is the
super nano multi-layered RF using the combination of the structural and
molecular orientation birefringence for wide-viewing LCDs. Keywords: Retardation / Optical Film / Birefringence / Wide-Band / Dispersion / Refractive Index / Nano Structure / Multi-Layer |

utilized the original large-area microwave plasma CVD method sustained
by surface waves for the large-area and low-temperature synthesis of
graphene. Graphene has been successfully obtained by this technique,
and a capacitive touch panel was produced demonstrating the successful
use of graphene. The roll-to-roll synthesis of graphene has been established
by using this low-temperature CVD technique. Keywords: Graphene / Microwave Plasma CVD / Low Temperature / Large Area / Transparent Conductive Sheet / Touch Panel / Roll-to-Roll Synthesis |

| ＜要旨＞ We
have developed a graded index plastic optical fiber (GI POF) based on
a partially chlorinated polymer (PCP). This polymer is a highly transparent
and high Tg material for GI POF due to hydrogen substitution in a polymer
chain with chlorine. The PCP GI POF can be an adequate medium for a high

| 三次元ベクトル波メモリの開発 Development of Three-Dimensional Vector Wave Recording |
福田 隆史・茨田 大輔・谷田貝 豊彦 Takashi FUKUDA, Daisuke BARADA, Toyohiko YATAGAI |
| ＜要旨＞ Here
we introduce dual-channel polarization holography as an optical recording
technique for three-dimensional vector wave memory. In dual-channel polarization
holography, two orthogonally polarized signal beams with two individual
images are superposed, and coupled with a reference beam on a recording
medium. Then, the interference pattern consists of intensity and polarization
pattern. Therefore, a polarization-sensitive medium must be used as a
recording medium. In order to verify the operating principle of dual-channel
polarization holography, two page data consist of p- and s-polarized
beams were simultaneously recorded on the medium. The reference beam
was set to s-polarized beam. When s-polarized readout beam is illuminated
onto the recorded medium, the recorded two images are simultaneously
reconstructed, and the two images can individually be extracted by a
polarizing beam splitter. From the experimental results, the operating
principle was verified. Keywords: Three-Dimensional Vector Wave Recording / Dual-Channel Polarization Holography / Page-Data Recording / Angular Multiplexing / Huge Capacity / Ultra High-Speed Data Rate / Polarization-Sensitive Medium / Optical Data Storage |

| メタセシス重合を用いた等間隔分岐高分子の合成 Precision Polymer Synthesis via Olefin Metathesis Polymerization |
小林 慎吾 Shingo KOBAYASHI |
| ＜要旨＞ The
recent development of olefin metathesis catalysts has expanded the scope
of olefin metathesis polymerization and the polymerization method has
already been a popular topic in the area of the polymer synthesis. Since
the recent olefin metathesis catalysts (e.g., Grubbs' catalyst) show
high functional group tolerance and high catalyst activity, olefin metathesis
polymerization has emerged as a powerful tool for synthesizing polymers
possessing functional groups as well as controlled molecular architectures.
Particularly, olefin metathesis polymerization allows synthesizing a
polymer exhibiting a quite unique molecular structure and having precisely
placed side-chain branches. This article provides a brief summary of
the investigators' reports on olefin metathesis chemistry. In addition
to tracing the historical development of metathesis polymerization, this
article covers the fundamental aspects of the method including both acyclic
diene metathesis polymerization (ADMET) and ring-opening metathesis polymerization (ROMP). Special attention is paid to the synthesis of polymers having
precisely placed side-chain branches via the metathesis polymerization,
ADMET and ROMP. Keywords: Olefin Metathesis / Metathesis Polymerization / ADMET / ROMP / Precisely Placed Side-Chain Branch / Regularly Branched Polymer / Precision Polyolefin / Regio- and Stereoselective ROMP |
