Question 4

Considering the industrial production and applications of polyethylene, which of the following statements correctly distinguishes between Low-Density Polyethylene (LDPE) and High-Density Polyethylene (HDPE)?

Accepted Answer

C. LDPE is produced via high-pressure free radical polymerization, leading to a highly branched molecular structure that results in lower density and greater flexibility, making it suitable for plastic films and squeeze bottles. In contrast, HDPE is synthesized using Ziegler-Natta or Phillips catalysts under lower pressure, yielding a more linear structure, higher density, and greater rigidity, ideal for milk jugs and pipes. — Option C accurately describes the differences. LDPE's highly branched structure, a result of high-pressure free radical polymerization, prevents close packing, leading to its lower density and flexibility, making it ideal for films. HDPE, produced with catalysts under lower pressure, has a more linear structure, allowing for denser packing, which results in higher rigidity and strength, suitable for items like milk jugs and pipes. Options A and B incorrectly swap the structural characteristics, production methods, and applications of LDPE and HDPE. Option D is incorrect because both LDPE and H

Answer

A. LDPE is formed under low pressure and temperature using Ziegler-Natta catalysts, resulting in a linear structure ideal for rigid pipes, while HDPE is produced via high-pressure processes, leading to branched structures suitable for flexible films.

Answer

B. HDPE is characterized by a high degree of branching in its polymer chains, making it less dense and more flexible for applications like plastic bags, whereas LDPE possesses a more linear structure, lending itself to rigid containers.

Answer

D. Both LDPE and HDPE are homopolymers of propene, but their differing densities arise from varying degrees of cross-linking, with LDPE having more cross-links for flexible applications and HDPE having fewer for rigid applications.

Question 5
