Which among the following is a condensation polymer commonly used in the manufacture of magnetic recording tapes and synthetic fibers?

💡 Solution & Explanation

Dacron, also known as Terylene, is produced via condensation polymerization between ethylene glycol and terephthalic acid, releasing water molecules as a byproduct. In contrast, polymers like polyethylene are formed through addition polymerization without byproduct elimination. Terylene fibers possess high crease resistance and strength, making them ideal for blended textile manufacturing.
