Question

Which among the following polymers is prepared by using Ziegler - Natta catalyst?

• A. HDPE
• B. LDPE
• C. Orlon
• D. Dacron

Hint:

The Ziegler-Natta catalyst is particularly useful for producing polymers like HDPE, which require controlled polymerization.

Answer 1

The Correct Option is A

Step 1: Understanding the Question.
The question is about the polymer prepared using Ziegler-Natta catalyst, which is a catalyst system used in polymerization reactions.
Step 2: Analyzing the options.
(A) HDPE: Correct — High-Density Polyethylene (HDPE) is synthesized using the Ziegler-Natta catalyst, which helps in the polymerization of ethylene.
(B) LDPE: Low-Density Polyethylene (LDPE) is made using free-radical polymerization, not Ziegler-Natta catalyst.
(C) Orlon: This is an acrylic polymer made from acrylonitrile, and it is not made using the Ziegler-Natta catalyst.
(D) Dacron: This polyester is made from terephthalic acid and ethylene glycol, and not through the Ziegler-Natta process.
Step 3: Conclusion.
The correct answer is (A) HDPE, as it is prepared using the Ziegler-Natta catalyst.
