Abstract: The necessity of modification of PET used as engineering plastics is introduced. Mainly for its low impact strength and poor crystallization properties, introducing the modified methods and the latest advances of PET. The methods include blending modification、nanocomposites modification and adding nucleating agent or nucleating accelerant, their mechanisms are simply introduced. At last, a summary on production and application of PET was given.
