Description
[ポリエステル重合体PBAT(poly(butylene adipate−co−terephthalate))の製造]
機械的撹拌装置とコンデンサーを装着した500mL 3口ガラスフラスコ(Pyrex(登録商標))にジメチルテレフタレート(dimethyl terephthalate、DMT)0.48mol、1,4−ブチレングリコール(1,4−butylene glycol、1,4−BD)1.3mol、触媒としてantimony trioxide 0.03g及びtetra−n−butyl titanate 0.2gを添加し、180℃で2時間エステル化反応を進行した後、さらにアジピン酸(adipic acid、AA)0.52molを投入し、1時間同一温度でエステル化反応をさらに進行した。その後、220℃で2Torr未満の真空で縮重合反応を200分間実施し、200gのポリエステル重合体を得た。
上記合成された重合体を高温真空乾燥器に入れ、20Torr以下、80℃で4時間以上真空乾燥させた。その後、カール・フィッシャー水分測定装備(C30 Compact Karl Fischer Coulometer)を利用して重合体内の含水率を測定した。
上記水分含量が調節された重合体200gに鎖延長剤としてジイソシアネート(hexamethylene diisocyanate)40mgを投入し、さらに酸化防止剤(Tetrakis[methylene(3、5−di−t−butyl−4−hydroxyhydrocinnamate)]methane、AO−60)40mg及びワックス(ethylene bis−stearamide、EBS)40mgを添加して混合した後、170℃で押出しながら反応させた。最終の生分解性樹脂を得た。
重合体の含水率の調節段階で調節される重合体の含水率及び重合体連結段階で鎖延長剤と酸化防止剤の種類及び量を下記表1のように異ならしめて使用することを除いて、実施例1と同一の過程によって生分解性樹脂を製造した。
市販の製品であるBASF社のecoflex BX7011を対照群として使用した。
実施例1〜6、比較例1及び2で収得された樹脂及び対照群として使用した比較例3の製品に対して溶融フロー指数(melting flow index(MFI))と分子量を測定した。
200g(重合体)+40mg(HMDI)+40mg(A0−60)+40mg(EBS)=200.12g
HMDI内に含まれた窒素の量:40mg×(28/168)=6.67mg
生分解性樹脂内の窒素の含量:6.67mg/200.12g=33ppm
実施例2及び4、比較例2及び3の生分解性樹脂を50mmフィルム押出器で幅42cm、厚さ35ミクロン(従量制ビニール袋20Lを基準)のフィルムに押出し、フィルムの色相、作業性及びフィルムの表面状態を比較・分析した。押出温度及び速度は、下記表3のように調整した。
