X-ray structure analysis was carried out in order to clarify the crystal structure and structural disorder of poly-(p-phenylenebenzobisthiazole). Two molecular chains pass through an oblique unit cell with parameters a Ο 11.60 Γ , b Ο 3.588 Γ , β₯ Ο 92.0Β°and the plane group p2. The angle between the ph
The high-speed melt spinning of poly(ethylene 2,6-naphthalene dicarboxylate ) ( PEN ) was performed up to the take-up velocity of the ultra-high-speed region, 9 km/min. From the investigations of the structure and physical properties of the asspun fibers, the high-speed spinning of PEN was divided i
