PMMA is the polymer of:

Options

A. Methyl methacrylate
B. Methyl acrylate
C. Methacrylate
D. Ethylacrylale

Answer

To determine the polymer of PMMA, we can follow these steps:

### Step 1: Identify the Full Name of PMMA
PMMA stands for Poly Methyl Methacrylate.

### Step 2: Identify the Monomer
The monomer that polymerizes to form PMMA is Methyl Methacrylate.

### Step 3: Write the Chemical Structure of the Monomer
The chemical structure of Methyl Methacrylate can be represented as:
- It has a double bond (C=C) and a carbonyl group (C=O) attached to a methyl group (CH3).

### Step 4: Understand the Polymerization Process
PMMA is formed through a process called free radical polymerization. This involves the following:
- The double bond in the monomer opens up and links with other monomer units to form a long chain (polymer).

### Step 5: Write the Repetitive Unit of PMMA
The repetitive unit of PMMA can be represented as:
- (C5H8O2)n, where 'n' indicates the number of repeating units.

### Step 6: Identify Applications of PMMA
PMMA is known for its transparency and rigidity, making it an excellent substitute for glass in various applications such as:
- Shutterproof windows
- Skylights
- Other products requiring a durable, clear material.

### Final Answer
PMMA is the polymer of Methyl Methacrylate.
