本発明に用いられるポリアリーレンスルフィド樹脂(A)は、芳香族環と硫黄原子とが結合した構造を繰り返し単位とする樹脂構造を有するものであり、具体的には、下記一般式(1)
本発明に用いるポリアリーレンスルフィド樹脂(A)は、300℃で測定した溶融粘度(V6)が2~1000〔Pa・s〕の範囲であることが好ましく、さらに流動性および機械的強度のバランスが良好となることから10~500〔Pa・s〕の範囲がより好ましく、特に60~200〔Pa・s〕の範囲であることが特に好ましい。但し、本発明において、溶融粘度(V6)は、ポリアリーレンスルフィド樹脂を島津製作所製フローテスター、CFT-500Dを用い、300℃、荷重:1.96×106Pa、L/D=10(mm)/1(mm)にて、6分間保持した後に溶融粘度を測定した値とする。

[工程1]
圧力計、温度計、コンデンサ、デカンタ、精留塔を連結した撹拌翼付き150リットルオートクレーブにp-ジクロロベンゼン(以下、「p-DCB」と略記する。)33.222kg(226モル)、NMP3.420kg(34.5モル)、47.23質量%NaSH水溶液27.300kg(NaSHとして230モル)、及び49.21質量%NaOH水溶液18.533g(NaOHとして228モル)を仕込み、撹拌しながら窒素雰囲気下で173℃まで5時間掛けて昇温して、水27.300kgを留出させた後、オートクレーブを密閉した。脱水時に共沸により留出したp-DCBはデカンターで分離して、随時オートクレーブ内に戻した。脱水終了後のオートクレーブ内は微粒子状の無水硫化ナトリウム組成物がp-DCB中に分散した状態であった。この組成物中のNMP含有量は0.079kg(0.8モル)であったことから、仕込んだNMPの98モル%(33.7モル)がNMPの開環体(4-(メチルアミノ)酪酸)のナトリウム塩(以下、「SMAB」と略記する。)に加水分解されていることが示された。オートクレーブ内のSMAB量は、オートクレーブ中に存在する硫黄原子1モル当たり0.147モルであった。仕込んだNaSHとNaOHが全量、無水Na2Sに変わる場合の理論脱水量は27.921gであることから、オートクレーブ内の残水量878g(48.8モル)の内、609g(33.8モル)はNMPとNaOHとの加水分解反応に消費されて、水としてオートクレーブ内に存在せず、残りの269g(14.9モル)は水、あるいは結晶水の形でオートクレーブ内に残留していることを示していた。オートクレーブ内の水分量はオートクレーブ中に存在する硫黄原子1モル当たり0.065モルであった。
上記脱水工程終了後に、内温を160℃に冷却し、NMP46.343kg(467.5モル)を仕込み、185℃まで昇温した。オートクレーブ内の水分量は、工程2で仕込んだNMP1モル当たり0.025モルであった。ゲージ圧が0.00MPaに到達した時点で、精留塔を連結したバルブを開放し、内温200℃まで1時間掛けて昇温した。この際、精留塔出口温度が110℃以下になる様に冷却とバルブ開度で制御した。留出したp-DCBと水の混合蒸気はコンデンサーで凝縮し、デカンターで分離して、p-DCBはオートクレーブへ戻した。留出水量は228g(12.7モル)であった。
工程3開始時のオートクレーブ内水分量は41g(2.3モル)で、工程2で仕込んだNMP1モル当たり0.005モルで、オートクレーブ中に存在する硫黄原子1モル当たり0.010モルであった。オートクレーブ内のSMAB量は工程1と同じく、オートクレーブ中に存在する硫黄原子1モル当たり0.147モルであった。次いで、内温200℃から230℃まで3時間掛けて昇温し、230℃で1時間撹拌した後、250℃まで昇温し、1時間撹拌した。内温200℃時点のゲージ圧は0.03MPaで、最終ゲージ圧は0.40MPaであった。冷却後、得られたスラリーの内、650gを3リットルの水に注いで80℃で1時間撹拌した後、濾過した。このケーキを再び3リットルの温水で1時間撹拌し、洗浄した後、濾過した。この操作を4回繰り返した。このケーキを再び3リットルの温水と、酢酸を加え、pH4.0に調整した後、1時間撹拌し、洗浄した後、濾過した。このケーキを再び3リットルの温水で1時間撹拌し、洗浄した後、濾過した。この操作を2回繰り返した。熱風乾燥機を用いて120℃で一晩乾燥して白色の粉末状のPPS樹脂(A-1)を得た。このポリマーの300℃における溶融粘度は41Pa・sであった。非ニュートン指数は1.07であった。
「次いで、内温200℃から230℃まで3時間掛けて昇温し、230℃で1時間撹拌した後、250℃まで昇温し、1時間撹拌した。」とする部分を「次いで、内温200℃から230℃まで3時間掛けて昇温し、230℃で1.5時間撹拌した後、250℃まで昇温し、1時間撹拌した。」としたこと以外は製造例1と同様にして、白色の粉末状のPPS樹脂(以下、A-2)を得た。得られたポリマーの溶融粘度は73Pa・s、非ニュートン指数が1.07であった。
圧力計、温度計、コンデンサを連結した撹拌翼および底弁付き150リットルオートクレーブに、フレーク状硫化ソーダ(60.3重量%Na2S)19.413kgと、NMP45.0kgを仕込んだ。窒素気流下攪拌しながら209℃まで昇温して、水4.644kgを留出させた(残存する水分量は硫化ソーダ1モル当り1.13モル)。その後、オートクレーブを密閉して180℃まで冷却し、パラジクロロベンゼン22.185kg、1,2,4-トリクロロベンゼン0.027kg及びNMP18.0kgを仕込んだ。液温150℃で窒素ガスを用いてゲージ圧で0.1MPaに加圧して昇温を開始した。液温240℃で2時間保持したのち、液温260℃で3時間攪拌しつつ反応を進め、オートクレーブ上部を散水することにより冷却した。次に降温させると共にオートクレーブ上部の冷却を止めた。オートクレーブ上部を冷却中、液温が下がらないように一定に保持した。反応中の最高圧力は、0.85MPaであった。反応後、冷却し、温度170℃の時点でシュウ酸・2水和物0.284kg(2.25モル)をNMP0.663kgに含む溶液を加圧注入した。30分間撹拌後、冷却し、100℃で底弁を開き、反応スラリーを150リットル平板ろ過機に移送し120℃で加圧ろ過したのち、NMP16kgを加え、加圧ろ過した。ろ過後、撹拌翼付き150リットル真空乾燥機を用いて、減圧下150℃で2時間撹拌してNMPを除去し、白色の粉末状のPPS樹脂(A-3)を得た。 このポリマーの300℃における溶融粘度は77Pa・sであった。非ニュートン指数は1.25であった。
圧力計、温度計、コンデンサを連結した撹拌翼および底弁付き150リットルオートクレーブに、フレーク状硫化ソーダ(60.3重量%Na2S)19.413kgと、NMP45.0kgを仕込んだ。窒素気流下攪拌しながら209℃まで昇温して、水4.644kgを留出させた(残存する水分量は硫化ソーダ1モル当り1.13モル)。その後、オートクレーブを密閉して180℃まで冷却し、パラジクロロベンゼン23.211kg及びNMP18.0kgを仕込んだ。液温150℃で窒素ガスを用いてゲージ圧で0.1MPaに加圧して昇温を開始した。液温260℃で3時間攪拌しつつ反応を進め、オートクレーブ上部を散水することにより冷却した。次に降温させると共にオートクレーブ上部の冷却を止めた。オートクレーブ上部を冷却中、液温が下がらないように一定に保持した。反応中の最高圧力は、0.85MPaであった。
