A copolyester is a copolymer synthesized by modification of polyesters, which are combinations of diacids and diols.

Copolyester is the modified form of polyesters, which are combinations of diols and diacids. For instance, if we introduce diacids, like isophthalic acid, or diols, like cyclohexane dimethanol to the polyester polyethylene terephthalate (PET), the material turns into a copolyester.

A copolyester obtained by polymerising 60 mol% of HBA and 40 mol% of polyethylene terephthalate (hereafter referred to as PET/HBA:40/60) is a raw material of commercial interest from the viewpoint of production cost.
