Which risk increases when high molecular weight polymers undergo sonication?

💡 Explanation

Chain scission and depolymerization raises because acoustic cavitation causes extreme local energy that fractures chains. Therefore, molar mass declines because sonication's mechanical stress overcomes covalent bonds rather than only affecting intermolecular van der Waals forces.
