Synthetic Polyesters Chemistry Tutorial - AUS-e-TUTE

Polyesters formed from a diol and a dicarboxylic acid are linear, that is, consist mainly of straight chains with few branches. Polyesters can be drawn out into fibres or stretched into films. The C=O bond in the ester link is polar, C δ+ =O δ-. Dipole-dipole interactions act between the polymer chains, C δ+ =O δ-.
