General description

1,4-Cyclohexanedicarboxylic acid (1,4-CHDA) has cyclohexane based structure. CHDA has better weatherability, higher impact strength, and faster stress relaxation. CHDA exhibits three isomeric forms:
  • axial, axial (a,a) trans-isomer
  • equatorial, equatorial (e,e) trans-isomer
  • a,e cis-isomer

Application

1,4-Cyclohexanedicarboxylic acid may be used in the synthesis of:
  • polyesters
  • polyamides
  • poly(butylene adipate-co-butylene 1,4-cyclohexanedicarboxylate) copolyester
  • various polyester polyols
