The research progress in melt blend modification of recycled polyethylene terephthalate(R-PET)was reviewed in China and abroad.The blend modification of R-PET was conducted with isocyanate and pyromellitic acid dianhydride as chain extender prior to blend melt extrusion,which can improve the relative molecular mass of R-PET.The blend modification of R-PET with organic polymers,such as traditional PET,polyolefin including polyethylene,polypropylene and their graft copolymers,polyearbenate and multieomponent mixture thereof,can improve the mechanical properties of the blend materials.The reinforced composites of R-PET can be the produced by the blend modification with glass fiber,basalt fiber and nano-organic clay.
