<ポリエステル(A)の製造方法>
テレフタル酸ジメチル100重量部とエチレングリコール60重量部とを出発原料とし、触媒として酢酸マグネシウム・四水塩0.09重量部を反応器にとり、反応開始温度を150℃とし、メタノールの留去とともに徐々に反応温度を上昇させ、3時間後に230℃とした。4時間後、実質的にエステル交換反応を終了させた。この反応混合物にエチルアシッドフォスフェート0.04重量部を添加した後、三酸化アンチモン0.04重量部を加えて、4時間重縮合反応を行った。すなわち、温度を230℃から徐々に昇温し280℃とした。一方、圧力は常圧より徐々に減じ、最終的には0.3mmHgとした。反応開始後、反応槽の攪拌動力の変化により、極限粘度0.63に相当する時点で反応を停止し、窒素加圧下ポリマーを吐出させた。得られたポリエステル(A)の極限粘度は0.63であった。
ポリエステル(A)の製造方法において、エチルアシッドフォスフェート0.04重量部を添加後、平均粒子径2μmのシリカ粒子を0.2重量部、三酸化アンチモン0.04重量部を加えて、極限粘度0.65に相当する時点で重縮合反応を停止した以外は、ポリエステル(A)の製造方法と同様の方法を用いてポリエステル(B)を得た。得られたポリエステル(B)は、極限粘度0.65であった。
