| 摘 要： | 研究了聚碳酸酯/超支化不饱和聚酯酰胺(PC/HUPEA)共混物的流动性能及力学性能与组成之间的关系,结果表明HUPEA能显著改善聚碳酸酯的流动性,对聚碳酸酯的力学性能也有影响.在0%～1.0%质量分数范围内,共混物拉伸模量和冲击强度随HUPEA的质量分数增加而下降;HUPEA的质量分数为0.43%时,拉伸强度和断裂伸长率都有最大值,而屈服强度最小. |

| Abstract: | The rheological and mechanical properties of PC / HUPEA blend are examined in this study,and the results demonstrate that replacing PC with hyperbranched unsaturated polyesteramide(HUPEA) causes large increase in the blend melt index and change in mechanical properties of the blend.The tensile modulus and the notched impact strength of the blend decrease with increase of HUPEA content,whereas the blend exhibit maximum values of tensile strength and breaking extension and a minimum value of yield strength as functions of HUPEA content when 0.43 wt % of the PC has been replaced. |
| Keywords: | hyperbranched polyesteramide polycarbonate melt index mechanical property |
