← ScienceWhich consequence results when ethylene polymerization employs a Ziegler-Natta catalyst?
A)Increased polymer chain branching stability
B)Decreased reaction system overall pressure
C)Stereoregular polymer chain formation✓
D)Exothermic chain-scission thermal runaway
💡 Explanation
Stereoregular polymers arise due to heterogeneous catalysis controlling monomer addition in a specific orientation, leading to highly ordered chains because the Ziegler-Natta mechanism promotes tacticity; therefore, a stereoregular polymer forms, rather than atactic branching or uncontrolled reactions.
