制造生物可降解聚酯树脂之方法;METHOD OF PREPARING BIODEGRADABLE POLYESTER RESIN

摘要

本发明提供一种制造生物可降解聚酯树脂之方法。制造生物可降解聚酯树脂之方法包括：(a)合成具有再加热结晶起始温度(Tch1)、再加热结晶峰值温度(Tch)及再加热结晶最终温度(Tch2)之生物可降解聚酯树脂；及(b)藉由使该树脂自温度T1冷却至温度T2，且接着维持该树脂在温度T2下持续时间tc来结晶在步骤(a)中合成的该生物可降解聚酯树脂。因此，可获得具有改良固化速率之生物可降解聚酯树脂。; and (b) crystallizing the biodegradable polyester resin synthesized in step (a) by cooling the resin from a temperature of T1to a temperature of T2and then maintaining the resin at a temperature of T2for a time of tc. Thus, the biodegradable polyester resin with improved solidification rate may be obtained.
