Influences of Bis-(2,6-Diisopropylphenyl) Carbodiimide on the Thermal Stability and Crystallization of Poly(P-Dioxanone)

摘要: ABSTRACTThe 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 addition St could significantly enhance stability crystallizability PPDO. The decomposition temperature PPDO increased with increase amount added. activation energies from 94.2 to 130.8 kJ mol−1 in case 5 wt% St. did not change crystal structure PPDO, while it number nucleation sites improved energies, calculated Kissinger method, for PPDO/5 wt% −111.4 −141.5 kJ mol−1, respectively, confirming enhanced after
