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.

Abstract: A thin film is provided, which includes a polymer formed by reacting (a) p-hydroxybenzoic acid, (b) 6-hydroxy 2-naphthoic acid and (c) branched-monomer. (c) branched-monomer is or a combination thereof, wherein R is aryl group, heteroaryl group, or cycloalkyl group, and each of R1 is independently —OH, —NH2, or —COOH. The molar ratio of (a) p-hydroxybenzoic acid over (b) 6-hydroxy 2-naphthoic acid is between 50:50 and 90:10. The molar ratio of (c) branched-monomer over the sum of (a) p-hydroxybenzoic acid and (b) 6-hydroxy 2-naphthoic acid is between 0.25:100 and 0.5:100. The polymer has an intrinsic viscosity of 4dL/g to 6dL/g.
