Which consequence results when the Arrhenius constant decreases significantly in polymer curing?

A)Faster polymer network chain scission
B)Extended polymer vitrification duration
C)Decreased material stress relaxation rate
D)Accelerated monomer diffusion coefficient increase

💡 Explanation

Decreasing the Arrhenius constant shifts the kinetic parameters, giving decreased curing rate; lower kinetic rates lead to the vitrification process extending because it reduces the number of crosslinks formed, therefore vitrification takes longer, rather than acceleration.
