Homopolymers and copolymers are the types of

Options

A. condensation polymers
B. addition polymers
C. linear polymers
D. branched polymers

Answer

### Step-by-Step Solution:

1. **Understanding Polymers**:
- Polymers are large molecules made up of repeating structural units called monomers.

2. **Definition of Homopolymers**:
- Homopolymers are a type of polymer that consists of only one type of monomer unit. This means that the same monomer repeats throughout the entire polymer chain.

3. **Examples of Homopolymers**:
- Common examples of homopolymers include:
- **Polystyrene**: Made from the monomer styrene.
- **Polyvinyl Chloride (PVC)**: Made from the monomer vinyl chloride.

4. **Definition of Copolymers**:
- Copolymers are polymers that are made up of two or more different types of monomer units. These different monomers can be arranged in various ways to form the polymer chain.

5. **Examples of Copolymers**:
- An example of a copolymer is:
- **Polyethylene Vinyl Acetate (EVA)**: This is formed from two different monomers, ethylene and vinyl acetate.

6. **Conclusion**:
- In summary, homopolymers consist of one type of monomer, while copolymers consist of two or more different types of monomers.
