Which statements are true describing the Ziegler-Natta process?
I. the process yields low density polyethylene
II. the process involves radicals
III. the original process used an alkytitanium catalyst
IV. the process yields polyethylene 3 to 10 times stronger than other methods

Question

Quizplus · Accepted Answer

The Ziegler-Natta process is known for producing high-density polyethylene (HDPE) and other types of polyolefins with high strength, not low-density polyethylene (I is false). It does not involve radicals but rather uses coordination polymerization (II is false). The original catalysts used in the Ziegler-Natta process were based on transition metals like titanium (III is true), and the process yields polyethylene that is significantly stronger than that produced by radical polymerization methods (IV is true).
