← ScienceWhich outcome occurs when high temperatures affect polymer chain interactions?
A)Reduced mechanical strength and elasticity✓
B)Increased crosslinking and rigidity
C)Enhanced thermal conductivity
D)Decreased chemical reactivity to solvents
💡 Explanation
High temperatures increase molecular motion, overcoming Van der Waals forces; therefore causing chain slippage via thermal expansion, and reduced strength, rather than greater crosslinking, because the Van der Waals interactions weaken. Thermal expansion weakens the hydrogen bonds.
