Poly(ethylene terephthalate) (PET) is widely used in synthetic fibers, beverage, food, and engineering plastics. However, melt foaming PET to produce the low‐density PET foams is faced with several challenges, especially low melt strength, due to its linear molecular structure. Hai‐Chao Yan, Hai‐Tao Yuan, Feng Gao, Ling Zhao, and Tao Liu modify fiber grade PET and recycled bottle grade PET to obtain chain extended PET with high viscoelasticity using a combination of reactive extrusion and solid‐state polycondensation. The cover is a cellular structure SEM image of the foamed product of modified recycled bottle grade PET. (DOI: 10.1002/app.42708 )
