Regarding the Ziegler-Natta catalyst used in the production of polyolefins like HDPE, which of the f — Polymers Chemistry Question

💡 Solution & Explanation

The Ziegler-Natta catalyst [$(C_2H_5)_3Al + TiCl_4$] allows ethene polymerization at low pressures ($6-7$ atm) and low temperatures ($333-343$ K) in a hydrocarbon solvent. It specifically yields linear (unbranched) polymers, which gives HDPE its high density.
