【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。更多还原

【Abstract】 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 are 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.更多还原
