Dacron is obtained by the condensation polymerization of:(A) dimethyl terephthalate and ethylene glycol(B) terephthalic acid and ethylene glycol(C) phenol and phthalic acid(D) phenol and formaldehyde

When phthalic anhydride and 1,2,3-propanetriol are heated together in equal molar amounts, they produce an amorphous polyester. In this reaction, polymerization selectively occurs at the primary hydroxyl groups of the triol. a)
