← ScienceWhich outcome occurs when a torsional load exceeds polyethylene's yield strength?
A)Covalent bond shear plane forms
B)Intermolecular chain slip occurs✓
C)Crosslinking density increases locally
D)Hydrogen bonding resists deformation
💡 Explanation
Intermolecular chain slip occurs because polyethylene chains slide past each other through disruption of Van der Waals forces upon exceeding its yield strength, therefore plastic deformation results, rather than bond breakage causing catastrophic failure.
