Studies on the Preparation of High Strength and High Modulus Poly(vinyl alcohol) Fiber (II) -Structure and Properties of Zone Drawn High Molecular Weight Poly(vinyl alcohol) Fiber-

고강도 및 고탄성률 폴리비닐알코올 섬유의 제조에 관한 연구 (II) -존연신된 고분자량 폴리비닐알코올 섬유의 구조 및 물성-

Recently, many attempts have been made to develop high strength and high modulus fibers from conventional polymers such as poly(vinyl alcohol) (PVA)[1-4] and polyethylene (PE). PVA has potentiality to yield high strength and high modulus fiber, since they have high theoretically attainable moduli because of their planar zig-zag structure. As PVA has a melting temperature as high as 230$^{\circ}C$ in contrast to PE with a low melting temperature such as 130$^{\circ}C$, it seems possible that high strength and high modulus fibers comparable to Aramid can be fabricated from PVA.
