## Abstract Xโray diffraction methods were employed to determine aโtriclinic unit cell that describes the crystal lattice of poly (__trans__โ1,4โcyclohexylenedimethylene terephthalate) (PCHDT). The crystal density was calculated as 1.265 g./cc., assuming one polymer repeat unit per unit cell. The f
The gas permeability and free volume of a series of polyester copolymers were studied. The free volume was studied using the positron annihilation lifetime spectroscopy (PALS) technique to indicate the relative size and concentration of free volume cavities in the copolymers. The homopolymers were p
## Abstract Infrared spectra have been recorded for __cis__ and __trans__ isomers of poly (1,4โcyclohexylenedimethylene terephthalate) (PCHDT). Infrared dichroisms were determined and band assignments were made. From spectra of polymers in both the crystalline and amorphous phases it was determined
