Description
攪拌翼を有する重合容器にp-ヒドロキシ安息香酸(HBA)60モル%、4,4’-ジヒドロキシビフェニル(BP)20モル%、テレフタル酸(TPA)15モル%、イソフタル酸(IPA)5モル%を加え、触媒として酢酸カリウムおよび酢酸マグネシウムを仕込んだ。重合容器の減圧-窒素注入を3回行って窒素置換を行った後、無水酢酸(水酸基に対して1.08モル当量)を更に添加し、150℃まで昇温し、還流状態で2時間アセチル化反応を行った。
アセチル化反応終了後、酢酸留出状態にした重合容器を0.5℃/分で昇温して、槽内の溶融体温度が305℃になったところで重合物を抜き出し、冷却固化した。得られた重合物を粉砕機により目開き2.0mmの篩を通過する大きさに粉砕して、プレポリマーを得た。
次に、上記で得られたプレポリマーを、固相重合装置に充填し、ヒーターにより320℃まで昇温した後、320℃で温度を1時間保持して固相重合を行った。その後室温で自然放熱し、粉末状の液晶ポリエステルAを得た。上記粉末状液晶ポリエステルAを350℃条件にて二軸押出機を用いペレットに加工したのち、同ペレットを成形温度350℃、金型温度100℃で射出成形し、試験片(30mm×30mm×厚さ1mm)を得た。
撹拌翼を有する重合容器にHBA60モル%、BP15モル%、TPA7モル%、IPA3モル%、アセトアミノフェン(AAP)5モル%、1,4-シクロヘキサンジカルボン酸(CHDA)10モル%を加えたこと以外、液晶ポリエステルAと同様の操作により液晶ポリエステルBを得た。
液晶ポリエスエルBに対して、フッ素樹脂(平均粒径:33μm)、カーボンブラック(一次粒子径:24nm)、炭素繊維(繊維長6mm)、酸化防止剤を所定の含有量となるように予め混合して混合物を得た。その混合物をエアーオーブン中で150℃にて2時間乾燥した。この乾燥した混合物を、シリンダー最高温度370℃に設定した二軸押出機のホッパーに供給し、15kg/hrにて、溶融混錬して、液晶ポリエステル組成物のペレットを得た。上記ペレットを成形温度350℃、金型温度100℃で射出成形し、試験片(30mm×30mm×厚さ1mm)を得た。
