    • A process for producing a wholly aromatic polyester which is excellent in heat resistance, mechanical properties and yet color and has a high degree of polymerization by melt polymerizing a dicarboxylic acid and a diol directly on an industrial scale at a low cost in a short period of time without esterifying the dicarboxylic acid or diol in advance. To produce the wholly aromatic polyester by reacting and molding an aromatic dicarboxylic acid such as terephthalic acid, an aromatic diol such as 2,2-bis(4-hydroxyphenyl)propane and a diaryl carbonate by heating, a combination of a specific pyridine compound and an alkali metal (bi)carbonate, a combination of a specific pyridine compound and an organic tin compound or a specific titanium compound is existent as a catalyst. Thereby, the wholly aromatic polyester having the above properties is obtained.

    • A process for manufacturing a carbon fiber having a fiber diameter of 0.001 to 5 μm and a narrow fiber size distribution, and a resin composition suitable for the manufacture of a carbon fiber. A resin composition comprising 100 parts by weight of a thermoplastic resin, 1 to 150 parts by weight of a carbon precursor organic compound (A) and 0.001 to 40 parts by weight of acopolymer of polymer segments (e1) and (e2) which satisfy a specific range of surface tension for the thermoplastic resin and a specific range of surface tension for the carbon precursor organic compound (A) at the same time. A process for manufacturing a carbon fiber, comprising the steps of producing a molded article of a precursor fiber (B) by treating the resin composition, subjecting the carbon precursor organic compound (A) contained in the precursor fiber (B) to a stabilization treatment so as to produce a stabilized precursor fiber (C), removing the thermoplastic resin contained in the stabilized precursor fiber (C), and carbonizing or graphitizing a fibrous carbon precursor (D) obtained by removing the thermoplastic resin.
    • 一种纤维直径为0.001〜5μm,纤维尺寸分布窄的碳纤维的制造方法以及适于制造碳纤维的树脂组合物。 一种树脂组合物,其包含100重量份的热塑性树脂,1至150重量份的碳前体有机化合物(A)和0.001至40重量份的聚合物链段(e1)和(e2)的共聚物,其满足 热塑性树脂的表面张力的特定范围和碳前体有机化合物(A)的同时具有特定的表面张力范围。 一种制造碳纤维的方法,包括以下步骤:通过处理树脂组合物,将前体纤维(B)中所含的碳前体有机化合物(A)进行稳定化处理,制备前体纤维(B)的模制品 以制备稳定的前体纤维(C),除去稳定化的前体纤维(C)中所含的热塑性树脂,并且通过除去热塑性树脂而获得的纤维状碳前体(D)碳化或石墨化。
