Application

2,2,4,4-Tetramethyl-1,3-cyclobutanediol serves as a key component in creating advanced polyester materials, offering an alternative to conventional polycarbonates that include the harmful bisphenol A. This cyclic aliphatic diol monomer not only enhances the glass transition temperature and shock resistance of the resulting polyesters but also improves their transparency, impact strength, melt viscosity, and toughness. Commonly presented as a white crystalline powder, it is integral to the production of Eastman Tritan™ copolyester. The typical method for synthesizing this monomer involves the hydrogenation of 2,2,4,4-tetramethyl-1,3-cyclobutanedione in the presence of dihydrogen.
