← ScienceWhich outcome occurs when unsaturated molecular chains undergo vulcanization with sulfur compounds?
A)Increased elasticity via cross-linking✓
B)Decreased thermal stability due to degradation
C)Enhanced brittleness from chain scission
D)Reduced solvent resistance by solvation
💡 Explanation
When unsaturated molecular chains undergo vulcanization, sulfur cross-linking occurs because sulfur atoms form covalent bonds between polymer chains improving the material's elasticity & strength. Therefore, increased elasticity results, rather than degradation, brittleness, or reduced solvent resistance with improper reactions.
