← ScienceWhich outcome commonly results when excessive mechanical stress fractures polymer chains?
A)Reduced tensile strength observed macroscopically✓
B)Increased crystallinity reflected in diffraction
C)Hydrophobic domains promote self-assembly
D)Enhanced material flexibility within specifications
💡 Explanation
Applying stress can cause chain scission because the mechanical energy exceeds bond energy, therefore reducing overall strength rather than enhancing it, where microscopic orientation changes or hydrophobic organization occurs under different thermal conditions, rather than breakage.
