However, the Izod impact strength of PHB can not be improved in this way. 6. Adding plasticized PPC, a good toughener for PHB, into PHB can change its fracture behavior from brittle to ductile, and increases the Izod impact strength from 36J/m for PHB to 307J/m for 70PHB/30PPC/20PGC.

增塑后的PPC是PHB的良好增韧剂，使PHB由脆性断裂转变为韧性断裂，最佳增韧效果可使PHB的抗冲击强度由36J/m增加到70PHB/30PPC/20PGC的307J/m，增加8倍。

Avrami and Ozawa equations were used to analyze the experiment data in this study. Because the melting point of PBS is high and the mechanical properties are worse. In addition, the PTS is uncrystallized. Therefore, PBS and PTS were mixed to improve their properties. PBS containing 5wt% PTS can be able to reduce the crystallization performance, and make the polymer strength to enhance. Furthermore, the brittle fracture situation of PBS is also improved simultaneously.

本研究运用等温结晶分析使用的Avrami 方程式以及Ozawa 方程式，分析实验所得的数据，因为PBS 的熔点较高，机械性能较差，加上PTS 几乎不结晶的特性，因此将PBS 及PTS 以不同比例混掺的方式，对PBS 进行分析研究，结果发现，加入5wt% PTS的共聚酯能够明显的降低结晶性能，进而使聚合物的拉伸强度提高，同时脆性断裂的情况也得到改善。
