摘要: The influences on the degradation of poly(p-dioxanone) (PPDO) under different temperature and relatively humidity is initially investigated by adding bis-(2,6-diisopropylphenyl) carbodiimide (commercial name: stabaxol®-1). changes intrinsic viscosity, mechanical properties, crystallinity, surface morphologies, microstructure PPDO containing stabaxol®-1 for 6 weeks are monitored. With increasing time, viscosity properties decrease much faster than those 0.6 wt % stabaxol®-1. During degradation, shows a better physical integrity PPDO. It has been shown that can retard hydrolysis enhance its hydrolytic stability. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2014, 131, 40026.
