Description
生分解性ポリエステルであって、モル百分率で、成分Aと、成分Bと、を含み、
成分Aは、繰り返し単位の酸成分として、テレフタル酸A1 40−48.5mol%と、セバシン酸A2 38.5−50mol%と、炭素鎖長が6以下の二塩基脂肪酸A3 2−20mol%と、を含み、成分Bは、ブタンジオールである。
二酸化炭素の保護下で、表1に示されるように、秤量したセバシン酸、炭素鎖長が6以下の二塩基脂肪酸、1,4−ブタンジオールを反応釜に投入して、撹拌しながら、200−210℃に昇温して1時間反応させ、次に、テレフタル酸、テトラキス(2−エチルヘキシル)チタネートを加えて、220−230℃に昇温して1−2時間反応させ、真空吸引して、2時間内で反応釜の内部の圧力を100Pa以下に低下させ、230−260℃で2−4時間反応させ、撹拌を停止して、反応釜へ二酸化炭素を導入し、樹脂を反応釜から押し出して造粒し、生分解性ポリエステルを得る。セバシン酸、炭素鎖長が6以下の二塩基脂肪酸、1,4−ブタンジオール及びテレフタル酸の投入量を変えると、さまざまな構造の樹脂が得られる。
メルトインデックス:試験条件 190℃、2.16Kgの分銅。
膜引張試験方法:生分解性ポリエステルを25±1μmの薄膜に製造して、ISO 527の標準に準じて試験を行った。
引張特性保持率:薄膜を40℃、85%の相対湿度で一ヵ月処理し、初期引張特性及び処理後の引張特性を試験した。引張特性保持率=処理後の引張特性/初期引張特性。
特性結果を表2及び3に示した。
