← ScienceWhich consequence results when disulfide bridges break in adhesives?
A)Reduced material tensile stress✓
B)Increased surface energy adhesion
C)Enhanced covalent crosslinking density
D)Weakened hydrophobic molecular association
💡 Explanation
Reduced material tensile stress results, because adhesive strength relies on disulfide bridges maintaining polymer network integrity; this breakage leads to chain slippage—a form of polymer degradation—rather than increased adhesion; therefore, stress declines.
