    摘要: 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 a copolymer constituted of polymeric segments (e1) and (e2) which have surface tensions against the thermoplastic resin and the organic compound (A) within specific ranges: and a process for the production of carbon fiber, characterized by producing a molding of a precursor fiber (B) from the composition, stabilizing the carbon-precursor organic compound (A) contained in the precursor fiber (B) to form a stabilized precursor fiber (C), removing the thermoplastic resin contained in the stabilized precursor fiber (C) to form a fibrous carbon precursor (D) free from the thermoplastic resin, and then subjecting the fibrous carbon precursor (D) to carbonization or graphitization.

    摘要: The present invention relates to a wholly aromatic polyester carbonate and a process for its production. An aromatic dicarboxylic acid, an aromatic diol, and a diaryl carbonate are used as starting materials in specific molar ratios, a prepolymerization step, a crystallization step, and a solid-phase polymerization step are essential steps, and a compression molding step is an optional step. This makes it possible to produce with good productivity a wholly aromatic polyester carbonate that has low coloration and a high degree of polymerization.

    摘要: 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.
