← ScienceWhich outcome occurs when ethylene gas undergoes polymerization within polyethylene production reactor?
A)Increased polymer chain branching
B)Catalyst poisoning from monomer depletion
C)Reduced tensile strength in product
D)Exothermic runaway reaction conditions✓
💡 Explanation
When ethylene polymerizes excessively, heat release from forming new covalent bonds surpasses cooling capacity because heat dissipates slowly from viscous materials, potentially causing a thermal runaway reaction. Therefore runaway conditions result, rather than solely impacting branching, catalyst activity, or tensile properties under controlled operations.
