← ScienceWhich risk increases when raising the reaction temperature of butadiene polymerization?
A)Increased generation of chain branching✓
B)Decreased initiation rate constant
C)Reduced stereochemical control ability
D)Consumption of the termination inhibitor
💡 Explanation
Elevated temperatures give reactants more energy promoting faster reactions, thus generating significant unwanted chain branching. Because chain addition occurs at a much greater rate, polymerization creates structural isomers rather than desired straight chains.
