Product Applications of 1,4-Cyclohexanedimethanol (CAS No. 105-08-8)
1,4-Cyclohexanedimethanol is an important precursor for polyester production. It serves as a key comonomer in the manufacture of polyethylene terephthalate (PET or PETE). In addition, it is used in the synthesis of polyketal copolymers and as a diol comonomer in the preparation of polyester-carbonates, such as those based on 1,3-propylene-co-1,4-cyclohexanedimethylene succinate.
