| ポリオレフィンの用途拡大と高機能化を可能とする表面改質 Surface Modification to Enable Wide Application and High Functionalization of Polyolefin |
金澤 等 Hitoshi KANAZAWA |
| ＜要旨＞ポリエチレンやポリプロピレンに代表されるポリオレフィンは軽量，安価，高強度であり，大量に消費されている。しかし，非極性で耐薬品性があり，改質困難な材料である。一般的な表面改質法と筆者が特許化した「活性化処理とモノマーまたは高分子処理」の組み合わせ法を述べて，処理試料を示した。その改質法はほかの加工困難な高分子にも適用できる。 Keywords: Polyolefin / Polyethylene / Polypropylene / Silicone Resin / Surface Modification / Water-Absorption / Adhesive and Painting Property / Solvent-Less Bonding |

野殿 光史・野田 哲也 Mitsufumi NODONO and Tetsuya NODA |
| ＜要旨＞ Properties
and/or functionalities of polymeric materials can be achieved by precise
control of side-chain groups, tacticities, main chain structures, segmented-block
structures and/or chain end groups. We briefly review some recent topics
on the control of primary structures of poly(methacrylates) by means
of
monomer architecture and metal-catalyzed polymerization to improve their properties and/or functionalities. Keywords: Methacrylic Polymers / PMMA / Tacticity / Stereo Specific / Cyclic Polymer / Block Copolymer / Catalytic Chain Transfer / Macromonomer |

吉留 正記 Masaki YOSHITOME |
| ＜要旨＞ Today
we produce a non-halogen flame retardant poly olefinic compound used
for wire and cable insulation. We usually evaluate a flame resistance
characteristic
of a material by a UL94V flame test or an oxygen index. Recently, we
are also studying the flame resistance capacity by the cone calorimeter
as
more quantitative evaluation method. Keywords: Non-Halogen / Flame Retardant / VW-1 / UL94 / Cone Calorimeter |

| バイオシリカに学ぶ階層構造材料 Biosilica Inspired Approach towards Construction of Hierarchically Structured Materials |
金 仁華 Ren-Hua JIN |
| ＜要旨＞ Silica
biomineralization occurs in water under ambient conditions for various
biological systems such as diatoms and sponges, producing exquisite hierarchical
structures and multiple morphologies with precise nano/microscale control.
This biosilicification inspired chemists and materials scientists to
mimick
the biosilica formation. An important issue in biosilicification is the role of organic matrices such as silaffin (polypeptides), silicatein (proteins) and long chain polyamine, which are indispensable in the formation of the silica frustule. A lot of efforts have been invested in using basic organic compounds and polyamines in silica deposition in order to understand biosilicification and to construct silica-based nanomaterials. Many new insights can be derived from mimicking biosilica using organic matrices. One is that the basic organic matrices employed in the biomimetic silicification have to be good catalysts for silica deposition and good templates for directing shaped silica. Another one is that crystalline aggregates, self-organized from linear polyethyleneimine [-CH2CH2NH-] entities, can act as efficient scaffolds, catalysts and templates directing complexly shaped nano-structured silica and nano-textured silica thin films.
