中文摘要in this paper, melt blends of poly(propylene carbonate) (ppc) with poly(butylene succinate) (pbs) were characterized by dynamic mechanical analysis (dma), differential scanning calorimetry (dsc), tensile testing, wide-angle x-ray diffraction (waxd), polarized optical microscopy and thermogravimetric analysis (tga). the results indicated that the glass transition temperature of ppc in the 90/10 ppc/pbs blend was decreased by about 11 k comparing with that of pure ppc. the presence of 10% pbs was partially miscible with ppc. the 90/10 ppc/pbs blend had better impact and tensile strength than those of the other ppc/pbs blends. the glass transition temperature of ppc in the 80/20, 70/30, and 60/40 ppc/pbs blends was improved by about 4.9 k, 4.2 k, and 13 k comparing with that of pure ppc, respectively; which indicated the immiscibility between ppc and pbs. the dsc results indicated that the crystallization of pbs became more difficult when the ppc content increased. the matrix of ppc hindered the crystallization process of pbs. while the content of pbs was above 20%, significant crystallization-induced phase separation was observed by polarized optical microscopy. it was found from the waxd analysis that the crystal structure of pbs did not change, and the degree of crystallinity increased with increasing pbs content in the ppc/pbs blends.
