浅谈硬质 PVC 的共混改性研究

摘要

The development history and the present situation of polyvinyl chloride were summarized.The research achievements were introduced about blending modification on PVC in domestic literature of science and technology in recent years.The technical progress was also introduced about blending modification on PVC in overseas patent in recent years.It was a effectual method that was proved by physical blending modification for improving process ability and mechanical ability of PVC.It was all the same active field of investigation was pointed out , wherever in domestic or in overseas, by using one or two even several macromolecule material as blending modifier of PVC.Author predict that new blending materials and new technology will come forth continuously , to meet the higher technique needs of blending materials of PVC, more broad application field will be brought for PVC.%简述了聚氯乙烯（ PVC）的发展历史和现状。介绍了近年来国内文献报导的PVC共混改性的研究成果，也介绍了近年来国外专利透露的PVC共混改性技术进展。证明共混物理改性是一种改善加工性能和提高力学性能的有效方法。指出了用一种或两种甚至多种高分子材料与PVC共混作为改性剂，不论是国内或是国外，目前仍是较活跃的研究领域。预见新的共混材料和新的工艺将不断出现，满足对PVC共混材料更高的技术要求，给PVC带来更广泛的应用领域。
