【摘要】 交联 PE/CPE 并用改性硬 PVC,可得到综合性能较佳的增韧硬 PVC 制品,但交联度和改性剂用量应适度。实验结果表明,共混方法对改性效果的影响显著,其中分段共混法较一步法增容效果好,制品性能较好。更多还原

【Abstract】 The toughened rigid PVC products with better properties can be obtainedby using crosslinked PE/CPE blend as a modifier,but the degree of cr-osslinking and the modifier dosage should be appropiate.The results showedthat the blending technology affected the properties of this blend greatly.Co-mpared with one-step blending,multi-stage blending can make the componentscompatible much better,thus the properties of the blend are improved.更多还原
