ポリハロゲン化芳香族化合物とは、1分子中にハロゲン原子を2個以上有する化合物をいう。具体例としては、p-ジクロロベンゼン、m-ジクロロベンゼン、o-ジクロロベンゼン、1,3,5-トリクロロベンゼン、1,2,4-トリクロロベンゼン、1,2,4,5-テトラクロロベンゼン、ヘキサクロロベンゼン、2,5-ジクロロトルエン、2,5-ジクロロ-p-キシレン、1,4-ジブロモベンゼン、1,4-ジヨードベンゼン、1-メトキシ-2,5-ジクロロベンゼンなどのポリハロゲン化芳香族化合物が挙げられ、好ましくはp-ジクロロベンゼンが用いられる。また、異なる2種以上のポリハロゲン化芳香族化合物を組み合わせて共重合体とすることも可能であるが、p-ジハロゲン化芳香族化合物を主要成分とすることが好ましい。
スルフィド化剤としては、アルカリ金属硫化物、アルカリ金属水硫化物、および硫化水素が挙げられる。
重合溶媒としては有機極性溶媒を用いるのが好ましい。具体例としては、N-メチル-2-ピロリドン、N-エチル-2-ピロリドンなどのN-アルキルピロリドン類、N-メチル-ε-カプロラクタムなどのカプロラクタム類、1,3-ジメチル-2-イミダゾリジノン、N,N-ジメチルアセトアミド、N,N-ジメチルホルムアミド、ヘキサメチルリン酸トリアミド、ジメチルスルホン、テトラメチレンスルホキシドなどに代表されるアプロチック有機溶媒、およびこれらの混合物などが挙げられ、これらはいずれも反応の安定性が高いために好ましく使用される。これらのなかでも、特にN-メチル-2-ピロリドン(以下、NMPと略記することもある)が好ましく用いられる。
生成する(A)PPS樹脂に反応性の末端を形成させるか、あるいは重合反応や分子量を調節するなどのために、モノハロゲン化合物(必ずしも芳香族化合物でなくともよい)を、上記ポリハロゲン化芳香族化合物と併用することができる。
比較的高重合度の(A)PPS樹脂をより短時間で得るために重合助剤を用いることも好ましい態様の一つである。ここで重合助剤とは得られる(A)PPS樹脂の粘度を増大させる作用を有する物質を意味する。このような重合助剤の具体例としては、例えば有機カルボン酸塩、水、アルカリ金属塩化物、有機スルホン酸塩、硫酸アルカリ金属塩、アルカリ土類金属酸化物、アルカリ金属リン酸塩およびアルカリ土類金属リン酸塩などが挙げられる。これらは単独であっても、また2種以上を同時に用いることもできる。なかでも、有機カルボン酸塩、水、およびアルカリ金属塩化物が好ましく、さらに有機カルボン酸塩としてはアルカリ金属カルボン酸塩が、アルカリ金属塩化物としては塩化リチウムが好ましい。

有機極性溶媒中でスルフィド化剤とポリハロゲン化芳香族化合物とを200℃以上290℃未満の温度範囲内で反応させることにより(A)PPS樹脂を製造する。
(a)ポリハロゲン化芳香族化合物をアルカリ金属硫化物に対しモル比で過剰に添加した場合
