✦ Synopsis

The crystallization behaviour of a copolyester based on polyethylene terephthalate containing cyclohexanedimethanol groups was studied as a function of thermal and solvent treatment, Although the rate of crystallization as compared to homopolymer was reduced, a substantial amount of crystallinity could be introduced by prolonged treatment and a new orthorhombic crystal lattice with unit cell dimensions of a = 5.05/~, b = 7.1 A and c = 10.7 A was formed in the copolyester as compared to tfic triclinic in the homopolymer.
