Poly(ethylene-co-1,4-cyclohexane dimethylene terephthalate) The thermal and photochemical oxidation processes of a polyester based on poly(ethylene-co-l,4-cyclohexanedimethylene terephthalate) (PECT) with approximately 30% of 1,4-cyclohexanedimethanol have been studied by means of chemiluminescence [88], Also, the stabilization activity of some commercial antioxidants has been evaluated, and it has been related to hydroperoxide levels in the polymer.

Other statistical copolymers that have been found to exhibit isodimorphic behavior include poly()3-hydroxybutyrate-co-)3-hydroxyvalerate) [87, 88], poly (butylene terephthalate-co-butylene-2,6-naphthalate) [89], poly(butylene terephthalate-co-l,4-cyclohexane dimethylene terephthalate) [90], and poly(butylene terephthalate-co-cyclopentane dimethylene terephthalate) [90]. In all cases, measurable crystallinity was observed over the entire copolymer composition range. An abrupt transition in the crystal structure was detected at some intermediate composition and was correlated with a eutectic-Uke minimum in the melting temperature [87-90].

Note, as discussed in Reference 8, 1,3-dimethylenecyclohexane is some 10 kJ mol 1 more stable than its 1,4-isomer. The 1,3- and 1,4-dimethylene compounds are stabilized relative to the monomethylene compound by 19 and 9 kJmol-1, respectively, while the corresponding diketones are stabilized relative to the monoketone by some 7 and 4 kJmol-1. These results are consonant with the 1,3-bis-sp2 cyclohexanes being more stabilized than their 1,4-counterpart, but electrostatic destabilization affecting the /J-di ketone and not particularly the bismethylene compound. 

Ball and Hardwood (105a) reported an unusual cationic intra-intermolecular polymerization in the case of 1,4-dimethylene cyclohexane. The best catalyst was BF- gas in methvlene chloride solution at -78 to -40° C.
