Polyvinal Chloride (PVC) is a hard plastic that despite claims about its safety is still commonly used as a building material.

The monomer of Polyvinylchloride (PVC) is vinyl chloride!! which is simply a hydrogen atom replaced by a chlorine atom in ethylene (monomer for polyethylene) i.e CH2=CHCl. Hope this helps.
