← ScienceWhich mechanism explains high tensile strength polymers achieve?
A)Chain entanglement resists chain slippage✓
B)Increased crystallinity prevents deformation
C)High molecular weight reduces yielding
D)Stronger van der Waals attractions resist
💡 Explanation
Chain entanglement resists chain slippage when polymers exposed to mechanical forces, because it increases the energy required to separate molecules, therefore tensile strength is higher, rather than caused by inherent stiffness.
