Kinetics of Glycolysis of Poly (ethylene Terephthalate) by Shrinking-Core Model

, 2011
Poly (ethylene terephthalate) (PET) wastes were depolymerised using excess ethylene glycol (EG) in the presence of zinc acetate as transesterificaion catalyst. Influences of particle size, reaction temperature, weight ratio of ethylene glycol (EG) to PET

Swelling-assisted Modification of Poly(ethylene terephthalate) by Methacrylic Acid

, 1995
When a poly(ethylene terephthalate), PET, film is heated in an aqueous solution of methacrylic acid in the presence of hydrogen peroxide as an initiator, it is found that the weight of the film is increased.
