Abstract
Disclosed is a polyester comprised of 1,4-cyclohexanedimethanol, a major portion of 1,4-cyclohexanedicarboxylic acid and a minor portion of dimer acid. Films of this polyester exhibit an unobvious combination of flexibility and high melting point and are particularly adapted for packaging applications.
