← ScienceWhich consequence results when a polymer adhesive's intermolecular forces weaken?
A)Adhesive creep under tensile load✓
B)Increased hardness prevents surface wetting
C)Rapid exothermic polymer chain stiffening
D)Elimination hydroxyl adhesion through functionalization
💡 Explanation
Adhesive creep increases as intermolecular forces weaken, because polymer chains can slide past each other more easily via the van der Waals mechanism. Therefore, creep occurs, rather than maintaining its shape, as stiffer polymers or chemically bonded adhesives would.
