Orlon is a polymer of

Options

A. Styrene and butadiene
B. Teflon
C. Vinylchloride
D. Acrylonitrile

Answer

To determine what Orlon is a polymer of, we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Term "Polymer":**
- A polymer is a large molecule made up of repeating structural units called monomers. The term "poly" means many, and "mer" means part or unit.

2. **Identifying Orlon:**
- Orlon is a specific type of polymer. Its chemical name is Polyacrylonitrile.

3. **Breaking Down the Name "Polyacrylonitrile":**
- The prefix "poly" indicates that it is a polymer made from many units of acrylonitrile.
- The term "acrylonitrile" refers to the monomeric unit that makes up this polymer.

4. **Chemical Structure of Acrylonitrile:**
- The chemical structure of acrylonitrile is represented as CH2=CH-CN. This indicates that it contains a vinyl group (CH2=CH) and a cyano group (CN).

5. **Polymerization Process:**
- Orlon is formed through a process known as addition polymerization, where multiple acrylonitrile monomers are linked together to form the polymer chain.

6. **Catalyst Used:**
- The polymerization of acrylonitrile to form Orlon typically uses a peroxide catalyst to initiate the reaction.

7. **Final Structure of Orlon:**
- The resulting polymer structure from the polymerization of acrylonitrile can be represented as a long chain of repeating units of CH2-CH-CN.

8. **Applications of Orlon:**
- Orlon (Polyacrylonitrile) is known for its high tensile strength and is used in various applications, including in the aerospace industry.

### Conclusion:
Orlon is a polymer made from the monomer acrylonitrile (also known as vinyl cyanide).
