COVER STORY: Highlight Reviews
High Modulus & High Strength Polymers Takashi NISHINO
<Abstract>Ultimate tensile strength, Youngfs modulus, toughness of polymers were discussed from the view points of safe and security. Nowadays, these mechanical properties of polymers are found to be superior to those of metals and ceramics. Further reduction of structural defect will be expected for making good things better.

Fibrous Metal Ion Adsorbent Synthesized by Radiation Processing Masao TAMADA
<Abstract>Graft polymerization is a radiation processing which can impart a desired functional group into a trunk polymer. When a nonwoven fabric is selected as the trunk polymer of the graft polymerization, a fibrous metal adsorbent can be synthesized. The resulting fibrous adsorbent realizes extremely high flow rate in the metal ion adsorption. The present paper describes the characteristic of the fibrous adsorbent and the applications to removal of toxic metals and collection of useful metals.

Evaluation of Safety and Biocompatibility of Medical Devices and
Their Materials		 Ryusuke NAKAOKA and Toshie TSUCHIYA
<Abstract>Before utilizing medical devices, evaluating their safety is indispensable. When polymers are utilized for the medical devices, not only themselves but also their components such as monomers, catalysts and additives must be evaluated to estimate their safety as well as their biocompatibility by appropriate methods. Various studies on cell-polymer interaction provide valuable information to develop the safety and biocompatibility of materials utilized for medical devices.

A Friction Decreasing Material for Constructional Application Koichi OKAMOTO
<Abstract>Friction decreasing material for constructional application; FDMC mainly consist of cross-linked polymers, enabling it to absorb water and form hydrogels. The gel form in FDMC mediates a friction decrease between soil and applied constructional structures, providing the high level of lubrication performance. A wide variety of constructional systems with FDMC have been developed to address safety issues through the high lubrication performance.

Front-Line Polymer Science
Development of Monomers Contributing to Useful Applications to
Functional Materials		 Takeshi ENDO and Atsushi SUDO
<Abstract>Molecular design of new monomers is the important core of development of new functional materials. Several cyclic monomers such as amino acid N-carboxyanhydride (NCA), 1,3-benzoxazine, and some specific lactones are becoming essential monomers in the fields of biomaterials, aerospace materials, and high performance adhesives for electronics, respectively. Molecular designs of these monomers, their practical synthetic processes, and the current status as well as the future prospect of their applications to functional materials are demonstrated herein.
