概要

• 論文の詳細を見る

• Mesophase spherules produced at the initial stage of their formation in the synthetic isotropic pitch were observed microscopically as-produced in the pitch and after the isolation by the solvent extraction. The spheres which were all uni-chromic in the pitch became discuses after the isolation, to show blue or yellow elliptic and purple circular cross-section in the optical microscope. The solvent extracted discus had rod-like units which were arranged parallel with the shorter axis of discus. Based on above observation, alignment of hexagonal plane in the rod-like unit has been discussed. The extraction of the soluble fraction appears to shrink the length of rod, suggesting its location in the plane of the insoluble fraction.
