摘要
对不饱和超支化聚(酰胺-酯)(HBP)与聚氯乙烯(PVC)共混体系的力学性能和相形态结构进行了研究。研究结果表明,在聚氯乙烯中加入不饱和超支化聚(酰胺-酯)可以有效提高共混体系的拉伸强度,并且在100g PVC中加入3g HBP时共混体系的拉伸强度出现最大值,抗冲强度基本不变。扫描电子显微镜(SEM)研究结果证明了HBP和PVC相容性较好,且与测得的力学结果相一致。同时,利用氢键形成机理对其结果进行了解释。
The mechanical properties and morphology of unsatured hyperbranched poly （amide-ester） （HBP）/ PVC blends were examined, where the content of the HBP was varied between 0- 10g per 100g PVC. The tensile strength of the blends reached the maximum value and the impact strength of the blends attained the minimum value when the content of HBP was 3 g per 100 g PVC. The Scanning Electron Microscopy （SEM） indicated also that the compatibility of HBP and PVC arc better and in agreement with results of mechanical properties. Finally, the H-bonded interaction scheme was proposed to give the reasonable explanation of the experimental results.
