发泡 PET 研究进展

摘要

In this paper, the methods of improving the melt strength of polyethylene terephthalate ( PET ) which mainly contain solid phase polycondensation (SSP), long chain branching and so on are discussed.Mean-time, the research progress of such methods in domestic and abroad is discussed too.Finally, the latest progress in theory, application and the prospection of the PET foam is also introduced.%介绍了聚对苯二甲酸乙二醇酯（ PET）提高熔体强度的方法，主要有固相缩聚、长链支化等，讨论了各种方法的国内外研究情况，以及国内外在发泡理论、应用方面的最新进展，对PET发泡前景进行了展望。
