| 中文摘要 | polylactide (pla) is an attractive candidate for replacing petrochemical polymers because it is biodegradable. in this study, a specific pla 2002d was melt-mixed with a new plasticizer: glycerol monostearate (gms). the pla/gms blends with different ratios were analyzed by dynamic mechanical analysis and differential scanning calorimetry. although a slightly phase separation can be seen in dsc curves, the sem micrographs of the impact fracture surfaces of pla/gms blends had a relatively good separation and this phenomenon was in good agreement with their higher impact strength. the result showed that the adding of gms has enhanced the flexibility of pla/gms blends as compared to neat pla. the relationship between complex viscosity and angular frequency of the pla/gms blends exhibits that the melt viscosity substantially lower than that of neat pla. for example, at 10 rad/s, the melt viscosity of pla/gms (85/15) was reduced by about 7.2% compared to that of neat pla. the impact strength was changed from 4.7 kj/m(2) for neat pla to 48.2 kj/m(2) for 70/30 pla/gms blend.
