Description
(B)−CO−Ar2−CO−
(C)−X−Ar3−Y−
攪拌装置、トルクメータ、窒素ガス導入管、温度計及び還流冷却器を備えた反応器に、p−ヒドロキシ安息香酸994.5g(7.2モル)、テレフタル酸299.0g(1.8モル)、イソフタル酸99.7g(0.6モル)、4,4’−ジヒドロキシビフェニル446.9g(2.4モル)、無水酢酸1347.6g(13.2モル)及び1−メチルイミダゾール0.2gを入れ、反応器内のガスを窒素ガスで置換した後、窒素ガス気流下、攪拌しながら、室温から150℃まで30分かけて昇温し、150℃で1時間還流させた。次いで、1−メチルイミダゾール0.9gを加えた後、副生酢酸及び未反応の無水酢酸を留去しながら、150℃から320℃まで2時間50分かけて昇温し、トルクの上昇が認められた時点で、反応器から内容物を取り出し、室温まで冷却した。得られた固形物を、粉砕機で粉砕して、窒素雰囲気下、室温から250℃まで1時間かけて昇温し、250℃から285℃まで5時間かけて昇温し、285℃で3時間保持することにより、固相重合させた後、冷却して、粉末状の液晶ポリエステルを得た。この液晶ポリエステルの流動開始温度は、327℃であった。
非晶性樹脂としてポリエーテルスルホン(住友化学(株)の「スミカエクセルPES3600P」、ガラス転移温度225℃)と、鱗片状グラファイト(日本黒鉛工業(株)の「CSP」)と、炭素繊維(三菱レイヨン(株)の「パイロフィルTCTR−03164」)と、製造例1で得られた液晶ポリエステルと、マイカ((株)ヤマグチマイカの「AB25S」)とを、表1に示す割合で、タンブラーを用いて、混合した後、二軸押出機(池貝鉄工(株)の「PCM−30」)を用いて、340℃で溶融混練し、ペレット化した。得られたペレットを、温風循環式乾燥機を用いて、180℃で12時間乾燥した後、射出成形機(日精樹脂工業(株)の「PS40E−5ASE型)を用いて、シリンダー温度350℃、金型温度150℃で射出して、64mm(MD)×64mm(TD)×3mmの平板状の成形体を得た。
MDの収縮率=(金型キャビティのMDの長さ−成形体のMDの2辺の長さの平均値)/金型キャビティのMDの長さ×100
TDの収縮率=(金型キャビティのTDの長さ−成形体のTDの2辺の長さの平均値)/金型キャビティのTDの長さ×100
