← ScienceWhich risk increases during laser processing of polymers?
A)Reduced polymer chain scission
B)Increased monomer vapor pressure✓
C)Enhanced free radical recombination
D)Decreased orbital hybridization effects
💡 Explanation
Increased monomer vapor pressure results from bond breaking via photoexcitation; the mechanism is thermal degradation because orbital energy from the laser heats the polymer, therefore vaporization is favored rather than chain stabilization.
