摘要
介绍了采用反应挤出法,增加PET分子链长度/支化度和分子量的研究现状。综述了国内外有关PET微孔发泡的研究进展,并阐述了影响其微孔发泡的主要工艺参数。
The research status of increasing the chain-extending/branching degree and the molecular weight of polyethylene terephthalate （PET） by reactive extrusion was introduced. The research progress of PET microcellular foaming was reviewed at home and abroad,and the effects of main process parameters on PET microcellular foaming were introduced.
