Abstract: A production method includes a process (I) of heating a cyclic polyarylene sulfide composition under reduced pressure and a process (II) of heating and polymerizing a cyclic polyarylene sulfide composition. This simple method allows for production of a polyarylene sulfide of the higher molecular weight and can produce a polyarylene sulfide having a narrow molecular weight distribution, low gas generation and high industrial usability. Additionally, pelletization after the process (I) can produce a cyclic polyarylene sulfide pellet having ease of conveyance, excellent molding processability, less gas generation amount and high industrial usability.
Abstract translation: 制备方法包括在减压下加热环状聚芳硫醚组合物的方法（I）和加热和聚合环状聚芳硫醚组合物的方法（II）。 这种简单的方法允许生产较高分子量的聚芳硫醚，并且可以生产具有窄分子量分布，低气体产生和高工业可用性的聚芳硫醚。 另外，工序（I）之后的造粒可以制造出具有易于输送，优异的成型加工性，较少气体产生量和高工业可用性的环状聚芳硫醚丸粒。
