← ScienceWhich outcome occurs when a high-energy electron beam is directed onto a polymer sample with weak covalent cross-links?
A)Chain scission and degradation begin✓
B)Increased crystallinity due to annealing
C)Enhanced cross-linking by radical formation
D)Exothermic polymerization of surface monomers
💡 Explanation
When a high-energy electron beam strikes a polymer, chain scission occurs because incident electrons break covalent bonds directly, leading to degradation of chains and smaller molecular weight. Therefore, chain scission occurs, rather than increased crystallinity, enhanced cross-linking or polymerization, which require thermal activation or specific catalysts.
