Abstract:
A "click" polymerization of dialkynes that contain an ester linkages and diazides to has been performed to synthesize various polyesters, termed "click polyesters" with a high $\overline M _{\rm n}$ of 1.0 × 10(4) to 7.0 × 10(4) in an excellent yield. This polymerization accompanied a formation of 1,4-disubstituted triazoles in the polyester main chain by a Cu(I) catalyst. The triazole ring formation in the polyester main chain leads to improved thermal properties and enhancement of the even-odd effect of methylene chain length of the produced click polyesters. This report is the first report of the application of click chemistry to synthesize a series of polyesters under mild conditions.

Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
