Abstract
Polyesters based on unsaturated diols were prepared by the transesterification of diethyl adipate and diols: cis-2-butene-1,4-diol, and 2-butyn-1,4-diol. The obtained results assert that the transesterification method is a suitable procedure for the preparation of unsaturated polyesters (comparatively to the direct polycondensation method). Unsaturated polyesters prepared are having molecular weights Mw= 500–2000 and a low polydispersity. Characterization of these products were investigated by elemental analysis, GPC, IR, 1H-NMR, and TGA.
