翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Technora ： ウィキペディア英語版 Technora Technora is an aramid that is useful for a variety of applications that require high strength or chemical resistance. It is a brand name of the company Teijin. It was also used to suspend the NASA Mars rover Opportunity from its parachute during descent. ==Production== Technora is produced by condensation polymerization of terephthaloyl chloride (TCl) with a mixture of p-phenylenediamine (PPD) and 3,4'-diaminodiphenylether (3,4'-ODA).〔Stephanie Kwolek, Hiroshi Mera, Tadahiko Takata “High-Performance Fibers” in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. 〕 The polymer is closely related to Teijin's Twaron or DuPont's Kevlar. Technora is derived from two different diamines, 3,4'-ODA and PPD, whereas Twaron is derived from PPD alone. This relatively simple process uses only one amide solvent, and therefore spinning can be done directly after the polymer production. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Technora」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
