Which of the following intermolecular forces primarily contributes to the high tensile strength, hig — Polymers Chemistry Question

💡 Solution & Explanation

Dacron is a polyester. Unlike polyamides (Nylons) which rely on strong hydrogen bonding, the high tensile strength and crystallinity of polyester fibres like Dacron are primarily due to strong dipole-dipole interactions between the highly polar ester ($-COO-$) groups on adjacent linear chains.
