Which outcome occurs when high-energy radiation exceeds the molecular cohesive forces?

A)Photodissociation pathways dominate polymer degradation
B)Intermolecular forces enable chain scission
C)Crystallinity increases during radical polymerization
D)Cross-linking enhances material thermal stability

💡 Explanation

Photodissociation cleaves chemical bonds because the energy input exceeds bond strength, leading to polymer fragments and degradation; therefore photodissociation occurs rather than stabilization or crosslinking which would require lower energies and differing molecular interactions.
