18-50 We have seen that esters can be prepared by treatment of a carboxylic acid and an alcohol in the presence of an acid catalyst. Suppose you start instead with a dicarboxylic acid such as 1,6-hexanedioic acid (adipic acid) and a diol such as 1,2-ethanediol (ethylene glycol). Show how Fischer esteri?cation in this case can produce a polymer (a macromolecule with a molecular weight several thousand times that of the starting materials).
