    Abstract: This invention relates to a process for making at least one polyester comprising: (a) a dicarboxylic acid component comprising: (i) 70 to 100 mole % of terephthalic acid residues; (ii) 0 to 30 mole % of aromatic dicarboxylic acid residues having up to 20 carbon atoms; and (iii) 0 to 10 mole % of aliphatic dicarboxylic acid residues having up to 16 carbon atoms; (b) a glycol component comprising: (i) 10 to 50 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues, which is a combination of greater than 80 mole % of cis-2,2,4,4-tetramethyl-1,3-cyclobutanediol and less than 20 mole % of trans-2,2,4,4-tetramethyl-1,3-cyclobutanediol, or greater than 85 mole % of cis-2, 2,4,4-tetramethyl-1,3-cyclobutanediol and less than 15 mole % of trans-2,2,4,4-tetramethyl-1,3-cyclobutanediol, or greater than 90 mole % of cis-2,2,4,4-tetramethyl-1,3-cyclobutanediol and less than 10 mole % of trans-2,2,4,4-tetramethyl-1,3-cyclobutanediol, or greater than 95 mole % of cis-2, 2,4,4-tetramethyl-1,3-cyclobutanediol and less than 5 mole % of trans-2,2,4,4-tetramethyl-1,3-cyclobutanediol; (ii) 50 to 90 mole % of cyclohexanedimethanol residues; and (iii) optionally, residues of at least one modifying glycol; wherein the total mole % of the dicarboxylic acid component of the final polyester is 100 mole %; wherein the total mole % of the glycol component of the final polyester is 100 mole %; and wherein the inherent viscosity of the final polyester is from 0.35 to 1.2 dL/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.25 g/50 ml at 25° C.; and wherein the final polyester has a Tg from 85° C. to 150° C.

    Abstract: The present invention relates to a thermoplastic polyether ester elastomer (TPEE) having a hard segment and a soft segment and a method for preparing the same and, more specifically, to a thermoplastic polyether ester elastomer and a method for preparing the same, wherein a unit derived from an anhydrosugar alcohol derivative with improved reactivity derived from biomass is contained in the soft segment, and thus through the adjustment of the content of the anhydrosugar alcohol derivative, elastic characteristics and physical characteristics (for example, hardness, etc.), which are important characteristics of an elastomer, can be favorably maintained, the melting point variously required in the molding process of a final product can be easily controlled, a problem of depletion of, especially, petroleum resources as finite resources, can be solved, and environmental friendliness can be improved.
