← ScienceWhich effect increases when polyethylene experiences chain scission?
A)Polymer chain mobility increases overall✓
B)Crystallinity within the plastic increases
C)Tensile strength increases substantially
D)Resistance to thermal creep is higher
💡 Explanation
Increased chain scission leads to shorter polymer chains; therefore, rotational freedom increases because the effect reduces the entanglement between polymer strands, rather than increased crystallinity.
