The polymer commonly known as PVC is Poly(chloroethene). This material is extensively used in various applications, including construction (for pipes and fittings), electrical cable insulation, and flooring due to its durability and resistance to degradation. The presence of chlorine atoms in the polymer chain significantly enhances its properties compared to its parent hydrocarbon polymer, ethene.

In the structure of Poly(chloroethene), the chlorine atoms provide additional strength and stability, making it more suitable for a range of industrial applications. Its versatility and cost-effectiveness contribute to its widespread use, differentiating it from other polymers that serve different functions and have varied properties.
