Dacron is classified mechanistically as a step-growth polymer. What is the stable, low-molecular-wei — Polymers Chemistry Question

💡 Solution & Explanation

During the condensation polymerization to form polyesters like Dacron or Glyptal, the hydroxyl ($-OH$) group of the diol reacts with the carboxyl ($-COOH$) group of the diacid to form an ester linkage ($-COO-$), with the accompanying elimination of a water ($H_2O$) molecule.
