← ScienceWhich outcome occurs when epoxy resins exhibit thermal degradation?
A)Chain scission reduces mechanical integrity✓
B)Increased crosslinking enhances impact resistance
C)Crystallization boosts chemical inertness
D)Volatiles emission reverses polymerization issues
💡 Explanation
As epoxy resin temperature increases, the rate of thermal degradation via chain scission increases because polymers degrade, destroying the covalent bonds rather than the crosslinking, therefore causing reduced structural integrity, rather than becoming more resistant because alternative chemical decomposition will ensue.
