| description | The invention provides a manufacturing method of polyester for a preservative film. The manufacturing method at least comprises the following steps. Aromatic carboxylic acid, aliphatic carboxylic acid and aliphatic alcohol are provided, wherein the aromatic carboxylic acid comprises at least two of phthalic acid, isophthalic acid and terephthalic acid. Aromatic carboxylic acid, aliphatic carboxylic acid and aliphatic alcohol are at least sequentially subjected to esterification reaction, prepolymerization reaction and polymerization reaction to obtain the poly (butylene adipate-co-terephthalate).
本发明提供一种用于保鲜膜的聚酯的制造方法，至少包括以下步骤。提供芳香族羧酸、脂肪族羧酸与脂肪族醇，其中芳香族羧酸包括邻苯二甲酸、间苯二甲酸、对苯二甲酸中的至少二者。藉由芳香族羧酸、脂肪族羧酸与脂肪族醇至少依序进行酯化反应、预聚反应、聚合反应，以获得聚己二酸对苯二甲酸丁二醇酯。 |
