Polyesters display a wide array of properties and practical applications. Permanent-press fabrics, disposable soft-drink bottles, compact discs, rubber tires, and enamel paints represent only a few of the products made from this group. Polyesters most commonly are prepared from a condensation reaction between an organic alcohol (containing hydroxyl [OH] groups) and a carboxylic acid (containing carboxyl...
