Description
本発明者らは、チタン触媒を用いたポリエステル樹脂の重合条件の最適化と共に、テレフタル酸などの重合原料自体の品質(特に、色調及び副産物の含量)を向上させることで、チタン触媒の使用時の短所を克服しようとした結果、ジメチルテレフタレート(DMT)を加水分解して得られる高純度テレフタル酸(HPTA)を重合原料として使用し、触媒構成及び反応条件を適切に制御すれば、色調とオリゴメール量が改善されたポリエステル樹脂を製造できることを見い出して本発明を完成するに至った。従って、本発明に係るポリエステル樹脂の製造方法は、チタン触媒の存在下において、ジメチルテレフタレートの加水分解により得られるテレフタル酸またはそのエステル誘導体を含むジカルボン酸成分とジオール成分とを反応させる工程を含む。
チップ(chip)状の樹脂試料0.36gを、濃度が1.2g/dlとなるようにo-クロロフェノール溶媒に150℃で15分間溶解した後、ウッベローデ粘度計を用いて35℃で原液との相対粘度(ηrel)を測定し、これから比粘度(specific viscosity)ηsp(=ηrel-1)を算出した後、ハギンス(Huggins)式を用いて樹脂の固有粘度(IV)を計算した。
試料0.1gを、濃度が1.0g/dlとなるようにベンジルアルコールに200℃で10分間溶解した後、窒素で冷却し、クロロホルム5mlを加えた後、標準化した0.1N NaOHを添加して、溶液が黄色から紅色になるまでのNaOH消耗量を求め、これからカルボン末端基値を計算した。
試料2gを混合酸で完全溶解した後、誘導結合プラズマ発光分光分析法によって金属原子の含量を求めた。
樹脂試料を円周上の測色用セル(cell)に一定量充填し、Lab表色系においてハンター(hunter)の彩度式色座標bを反射法にて3回測定して平均値を求めた。
樹脂を170℃で12時間真空乾燥し、射出成形機(ASB150、日精樹脂工業社製)に投入して、高さ145mm、外径28mm、厚さ4mm、重量48gのフリーフォームを射出ブロー成形(シリンダー温度275℃、成形サイクル23秒)した。得られたフリーフォーム本体部の色調をヘイズメーター(300A、日本電色社製)を用いて3回測定後、平均値を求めた。
色調測定時と同様にして製造したフリーフォームを凍結粉砕後、粉砕物約1gを20ml容器に入れ、150℃で40分間加熱して得られるアセトアルデヒドの量をガスクロマトグラフィーを用いて測定し、純粋なアセトアルデヒドの希釈液値と比較してその絶対値を求めた。
樹脂またはフリーフォーム試料をクロロホルム/ヘキサフルオロイソプロパノール混合溶媒に溶解後、クロロホルムを加えて希釈し、メタノールを加えて樹脂を再析出させた。溶液を蒸発乾燥した後、さらにジメチルホルムアミドで溶解後、環状3量体の量を液体クロマトグラフィーで定量した。
