Which consequence results when thermal stress causes chain scission?

💡 Explanation

Thermal stress may break covalent bonds in the polymer chains, a mechanism called chain scission; because chains shorten, causing reduction in entanglement leads to loss of mechanical strength and making the material weaker, therefore (A). Rather than (B), polymerization will not increase at lower temperatures.
