摘要： The production process of the present invention for polyarylene sulfide is characterized by that in a process for continuously producing polyarylene sulfide by reacting a sulfur source with a dihalogenated aromatic compound in an aprotic organic solvent, it comprises at least one polymerization reaction step in which two phases of a polymer phase and a solvent phase are separated and in which the polymer phase corresponding to a dispersion phase is a dispersion phase comprising globular droplets and that an end terminator is used in the above polymerization reaction step. According to the present invention, a polymer can be prevented from being adhered onto a polymerization reaction bath to thereby make it possible to discharge a polymer phase and a solvent phase from the polymerization bath in a constant proportion; resultingly, a PAS composition (concentration) in the polymerization bath can always be maintained at a constant value; and polyarylene sulfide having a raised and stabilized molecular weight can continuously be produced.

摘要： A polyether copolymer comprising the repeating units represented by the following general formula (I) ##STR1## and the repeating units represented by the following formula (II) ##STR2## the molar ratio of (I)/{(I)+(II)} being from 0.1 to 0.8 and the polyether copolymer having a melt viscosity of at least 500 poise as measured at 400.degree. C. is produced by allowing a dihalogenobenzonitrile, 1,4-bis(4'-halobenzoyl)benzene, and 4,4'-biphenol to react with each other in an aprotic polar solvent in the presence of an alkali metal compound. The polyether copolymer exhibits excellent heat-resistance, solvent resistance, and mechanical strength, and is suitable as a material for resin compositions, heat-resistant laminates, fiber, and film.

摘要： A process for continuous production of a branched polyarylene sulfide, which includes pre-polymerizing a sulfur source with a dihalogenated aromatic compound in such a manner that the reaction rate of the dihalogenated aromatic compound is less than 95% so as to produce a polyarylene sulfide, prepolymer, and polymerizing the prepolymer in the presence of a branching agent while dispersing the phase of the polymer into the form of spherical droplets in the phase of a solvent. When the prepolymer is added to the solvent phase to which a phase separator is beforehand added, spherical droplets of the polymer phase can be produced.
