The comercial name of polyacrylonitrile is ……

Options

A. dacron
B. orlon (acrilan)
C. PVC
D. bakelite

Explanation

To solve the question regarding the commercial name of polyacrylonitrile, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Polymer**: We start by recognizing that polyacrylonitrile is a type of polymer. Polymers are large molecules made up of repeating structural units called monomers.

2. **Determine the Monomer**: The monomer for polyacrylonitrile is acrylonitrile. This is the basic building block that, when polymerized, forms polyacrylonitrile.

3. **Understand the Polymerization Process**: Polyacrylonitrile is formed through a process called polymerization, where the monomer acrylonitrile undergoes a chemical reaction (often initiated by a catalyst like peroxide) to form the long-chain polymer.

4. **Find the Commercial Name**: The question specifically asks for the commercial name of polyacrylonitrile. The common commercial names associated with polyacrylonitrile are "Orlon" and "Acrylene."

5. **Conclude the Answer**: Therefore, the commercial name of polyacrylonitrile is "Orlon."

### Final Answer:
The commercial name of polyacrylonitrile is **Orlon**.
