Polyethylene Terephthalate Structure. In acidic medium, protonation of terephthalic acid occurs that reacts with ethylene glycol to form an intermediate which rearranges and with the transfer of OH- ions, forms polyethene terephthalate polymer. Overall both monomer units are joined together with ester linkage therefore commonly called as polyester.
