Which outcome results when thermal energy weakens intermolecular forces within a polymer?

A)Reduced glass transition temperature✓

B)Increased elastic modulus plateau

C)Cross-linking becomes thermodynamically favored

D)Crystallinity increases due to ordering

💡 Explanation

Thermal energy increases chain mobility promoting chain slippage, because the **weakening of van der Waals forces** surpasses energy of attraction; therefore, the glass transition temperature decreases, rather than increasing modulus, promoting cross-linking, or increasing crystallinity under these conditions.
