Which consequence results when excessive strain breaks polymer chains?

💡 Explanation

Breaking polymer chains lowers the average chain length, which undergoes a change in vibrational modes through **chain scission**. This decreases energy needed for the polymer to transition to a glassy state, therefore the transition decreases rather than increases under different stress conditions.
