Which bond alteration weakens a polymer's tensile strength?

💡 Explanation

Chain scission weakens tensile strength because the breaking of covalent bonds via oxidation shortens polymer chains and reduces molecular weight, therefore lowers the force required for deformation; rather than strengthening alternatives due to enhanced intermolecular bonding.
