What structural and physical characteristics are strictly associated with unvulcanized (raw) natural — Polymers Chemistry Question

💡 Solution & Explanation

Raw natural rubber is soft/sticky at high temps ($>335$ K), brittle at low temps ($<283$ K), has low tensile strength, and absorbs water. However, it is *soluble* in non-polar solvents, which is a property that vulcanization aims to eliminate.
