本発明は、特定のセグメント長とカルボキシル基含有量を有することで、従来の半芳香族ポリエステルと比較して、分解速度と機械的特性を両立させることができる半芳香族ポリエステルを提供する。本発明により得られる半芳香族ポリエステルの30日間の重量保持率を45~70%とすることができる。
半芳香族ポリエステルの粘度数:
GB/T 17931-1999に準じて、重量比1:1のフェノール/o-ジクロロベンゼン溶液中、25±0.05oCの恒温水浴中で測定し、試料濃度は5mg/mlであった。
まず、1998年10月のDIN EN 12634から酸価AN(mg KOH/g)を決定し、次に、カルボキシル基含有量(mmol/kg)=AN/56×103を決定した。使用される溶剤混合物は、DMSO 1体積部、プロパン-2-オール8体積部、トルエン7体積部を含む。半芳香族ポリエステルサンプルを50℃に加熱し、回路として単棒電極を用い、塩化カリウムを充填した。使用する標準溶液は水酸化テトラメチルアンモニウムであった。
Bruker社AV 400型核磁気共鳴スペクトロメータを用いて、重水素化クロロホルム(CDCl3)を溶媒、テトラメチルシラン(TMS)を内部標準として測定した。測定結果は王暁慧博士の学位論文32-34ページの方法を参考に分析計算してBa2セグメントの長さのデータを得た(王暁慧 脂肪族-芳香族コポリエステル合成新技術及び特性研究博士の学位論文,北京化工大学,2011.)。
半芳香族ポリエステルの生分解実験は19277 GB/T-2003を参照してテストした。まず、半芳香族ポリエステル試料を厚さ0.10mmのサンプルにして、2.0cm×1.2cmのサンプルに裁断して、このときのサンプルの重量をa0と記す。次に、サンプルを堆肥土壌に埋めてインキュベータに入れ、堆肥土壌は、56~70日間の曝気とふるい分けを経た都市ごみ堆肥であり、実験温度は(58±2)℃に維持されており、堆肥サンプルは30日後に取り出し、洗浄・乾燥して秤量し、このときのサンプル重量をa1と記す。この場合、30日間の重量保持率=a1/a0×100%である。30日間の重量保持率が高いほど、材料の劣化が難しくなり、30日間の重量保持率が低いほど、材料の劣化速度が速くなることを示す。
半芳香族ポリエステルを25±1μmのフィルムにし、ISO 527規格でテストした。
