Abstract: A copolyester is formed by copolymerizing a depolymerized polyester and succinic acid. The depolymerized polyester includes depolymerized polyethylene terephthalate (PET), and the depolymerized PET is formed by depolymerizing PET with ethylene glycol. The repeating unit of PET and the succinic acid have a molar ratio of 40:60 to 50:50. The repeating unit of PET and the ethylene glycol have a molar ratio of 100:100 to 100:500. The copolyester has a storage modulus of 1*104 Pa to 1*106 Pa at 80° C. The copolyester can be used in a hot melt adhesive.
