Description and Uses
2,2,4,4-tetramethyl-1,3-cyclobutanediol (CBDO) is a cyclic aliphatic diol monomer which is used to synthesize high-performance functionalized polyester materials as the alternative to traditional polycarbonate (PC) containing the poisonous bisphenol A. Additionally, incorporating CBDO compounds into the polyesters significantly improves the glass transition temperature of the materials and enhances their shock resistance. It also endows the polyesters with improved transparency, higher impact strength, higher melt viscosity and better toughness. To date, the major synthesis route to prepare CBDO is hydrogenation of 2,2,4,4-tetramethyl-1,3-cyclobutanedione (CBDK) in a dihydrogen atmosphere[1].
2,2,4,4-Tetramethyl-1,3-cyclobutanediol was used in the preparation of Eastman Tritan? copolyester.
