← ScienceWhich consequence results when molecular packing becomes strained in epoxy?
A)Reduced glass transition temperature✓
B)Increased thermal decomposition rate
C)Elimination of van der Waals forces
D)Enhanced resistance to chemical attack
💡 Explanation
A strained structure lowers the glass transition because chain mobility increases through reduced entanglement; therefore, its glassy properties weaken, rather than a chemical degradation from thermal decomposition, which requires significant energy input.
