摘要: The crystallization kinetics and crystalline structure of the biodegradable polymorphic polymers, poly(butylene adipate) (PBA) adipate-co-hexamethylene adipate), in microparticles nanoparticles covered by poly(vinyl alcohol) (PVA), those on PVA substrate were investigated differential scanning calorimetry, wide-angle X-ray diffraction, Fourier transform infrared spectroscopy. Both polymers crystallized particle state showed higher temperatures nonisothermal melt shorter times isothermal crystallization; this indicated a faster polymer than that bulk sample. Furthermore, preferential formation β-type form PBA compared to one. mechanism for effects layer or its copolyesters are discussed. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.
