(A) Terylene (Dacron) is a polyester fibre which is prepared by the condensation polymerization of ethylene glycol and terephthalic acid with the elimination of water molecules.The chemical reaction is:$nHOCH_2CH_2OH + nHOOCC_6H_4COOH \rightarrow [-OCH_2CH_2OCOC_6H_4CO-]_n + 2nH_2O$This reaction takes place at a temperature of about $425-475 \ K$ in the presence of a zinc acetate-antimony trioxide catalyst.
