Abstract: A polyester is formed by reacting a plurality of monomers. The monomers include 7 to 20 parts by mole of (a) aliphatic triol monomer, 40 to 80 parts by mole of (b) first diol monomer, 12 to 40 parts by mole of (c) second diol monomer, and 100 parts by mole of (d) aliphatic diacid monomer or aliphatic anhydride monomer. The (b) first diol monomer has a chemical structure of




wherein each R1 is the same. The (c) second diol monomer has a chemical structure of




wherein R6 is different from R7.
