Polyester and its production method |
| abstract |
PROBLEM TO BE SOLVED: To provide a high quality polyester having a small amount of a cyclic oligomer when melted. SOLUTION: A specific amount of a phosphorus compound having a hydroxyl group derived from phosphoric acid is blended with polyethylene terephthalate or a polyester mainly containing the specific amount of one or more metal atoms selected from antimony, titanium and nickel atoms. Thereby, a polyester having a small amount of a cyclic oligomer when melted is obtained. |
