Synthetic vs. Natural: Compare polysoprene (natural rubber) with synthetic polymers like SBR (Styrene-Butadiene Rubber), emphasizing their molecular structure differences.
War-Driven Innovation: Discuss how WWII shortages accelerated synthetic rubber production (e.g., Buna-S rubber), reducing reliance on tropical plantations.
Modern Applications: Showcase rubber’s use in aerospace seals, medical devices, and renewable energy components.
