Abstract:

The modification methods and foaming process of polyethylene terephthalate (PET) were reviewed. The modification methods include solid state polycondensation, in?situ copolymerization, and chain extension modification, and the foaming processes mostly involves autoclave foaming, molded?press foaming, extrusion foaming, etc. Moreover, the applications of PET foaming materials were briefly introduced.

Key words: polyethylene terephthalate, modification, foaming material
