The influences on the thermal degradation and crystallization behaviors of poly(p-dioxanone) (PPDO) were initially investigated by adding bis-(2,6-diisopropylphenyl) carbodiimide (labeled as St). It was found that the addition of St could significantly enhance the thermal stability and crystallizability of PPDO. The thermal decomposition temperature of PPDO increased with the increase of the amount of St added. The thermal decomposition activation energies of PPDO increased from 94.2 to 130.8 kJ mol⁻¹ in the case of 5 wt% St. The addition of St did not change the crystal structure of PPDO, while it increased the number of nucleation sites and improved the crystallizability of PPDO. The crystallization activation energies, calculated by the Kissinger method, for PPDO and PPDO/5 wt% St were −111.4 and −141.5 kJ mol⁻¹, respectively, confirming the crystallizability of PPDO was enhanced after the addition of St.

通过添加双-（2,6-二异丙基苯基）碳二亚胺（标记为St），初步研究了对聚对二氧杂环己酮（PPDO）的热降解和结晶行为的影响。发现添加St可以显着增强PPDO的热稳定性和结晶性。PPDO的热分解温度随着St的添加量的增加而增加。PPDO的热分解活化能从94.2增加到130.8 kJ mol ^-1在5wt％的St的情况下。St的添加没有改变PPDO的晶体结构，而增加了成核位点的数量并改善了PPDO的结晶性。通过Kissinger方法计算的PPDO和PPDO / 5 wt％St的结晶活化能分别为-111.4和-141.5 kJ mol ^-1，证实添加St.后PPDO的结晶性得到增强。
