Description

The anion-exchange fiber was prepared by radiation-induced emulsion graft polymerization of glycidyl methacrylate (GMA) on a polyethylene (PE) fiber and subsequent chemical modifications. The PE fiber was irradiated with electron beam at various doses ranging from 20 to 200 kGy before GMA was graft-polymerized. Subsequently, the epoxy group of the poly-GMA graft chain was converted into a diethylamino (DEA) group with a molar conversion of 89 to 93%. At the degrees of GMA grafting of 85±8%, the anion-exchange fibers prepared at various doses up to 200 kGy exhibited a molar ratio of amount of Cl adsorbed to DEA group density of unity irrespective of dose. In contrast, the anion-exchange fiber prepared at 20 kGy exhibited 3.4-fold higher amount of bovine serum albumin adsorbed than that prepared at 200 kGy. (author)

Abstract (Japanese)

ポリエチレン(PE)繊維へのグリシジルメタクリレート(GMA)の放射線前照射乳化グラフト重合及びそれに続く化学修飾によって,アニオン交換繊維を作製した。まず,PE 繊維へ20~200 kGyの範囲で電子線を照射し,GMA をグラフト重合した。続いて,GMA グラフト鎖中のエポキシ基をジエチルアミノ(DEA)基へ転化した。このときモル転化率は89~93%であった。線量を変えて,グラフト率85±8%の範囲で作製したアニオン交換繊維の,DEA 基密度に対する Cl吸着量のモル比は,線量によらず1 であった。一方,20 kGy で作製したアニオン交換繊維のウシ血清アルブミンの吸着量は,200 kGy で作製したアニオン交換繊維のそれに比べて3.4 倍高い値を示した。(著者)
