A homopolymer is a polymer where every monomer unit (mer) of the chain is the same.

Homopolymer Examples

Polyvinylchloride (PVC) is a homopolymer consisting of vinyl chloride units. Polypropylene consists of repeating propylene units.

In contrast, DNA is a polymer that is not a homopolymer. Different sequences of base pairs are used to encode genetic information.
