超临界二氧化碳中聚偏氟乙烯的合成

摘要

分别从沉淀聚合和分散聚合两方面介绍了以超临界二氧化碳为介质合成聚偏氟乙烯的概况，阐述了超临界聚合制备的聚偏氟乙烯在结构性能上的研究，认为超临界二氧化碳聚合的环境友好性、聚合可控性及聚合产物结构性能的独特性使其在未来的工业生产中具有一定的应用潜力。%The synthesis of polyvinylidene fluoride using supercritical carbon dioxide as the medium was described from dispersion polymerization and precipitation polymerization. The research on structure and property of polyvinylidene fluoride by supercritical polymerization was elaborated. Then it pointed out the polymerization of polyvinylidene fluoride in supercritical carbon dioxide had great potential in the future in-dustrial production for its environmental-friendly, controllability and specificity on polymer property and structure.
