Which risk increases when prolonged torsional stress fractures cross-linked polymer chains?

💡 Explanation

Chain scission is promoted by high stress, therefore the reduced glass transition occurs because lower molecular weight chains have reduced entanglement and flexibility, rather than enhanced crystal formation or entanglement, which are consequences of annealing.
