← ScienceWhich consequence results when thermal decomposition weakens inter-chain forces in polymers?
A)Reduced tensile strength develops markedly✓
B)Increased exothermic crosslinking initiates rapidly
C)Crystallinity increases at amorphous regions
D)Tacticity defects become uniformly corrected
💡 Explanation
Weakened van der Waals forces during thermal decomposition promotes chain slippage. Because decreased inter-chain interactions reduce the energy needed for deformation, therefore tensile strength diminishes, rather than increased crosslinking, which would enhance it.
