Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")
Polyvinyl chloride is formed in flat sheets in a variety of thicknesses and colors. As flat sheets, PVC is often expanded to create voids in the interior of the material, providing additional thickness without additional weight and minimal extra cost (see closed-cell PVC foamboard ).
Due to its toxic nature, vinyl chloride is not found in other products. Poly(vinyl chloride) (PVC) is very stable, storable and not toxic. [2] Until 1974, vinyl chloride was used in aerosol spray propellant. [7] Vinyl chloride was briefly used as an inhalational anaesthetic, in a similar vein to ethyl chloride, though its toxicity limited this use.
PVC and plastic production produces PVC dust [59] [60] with mortality confirmed among vinyl and polyvinyl chloride workers after reanalysis of data [61] and coronary artery disease and cancer death among vinyl chloride exposed workers [62] Rubber chemical manufacturing impacting mortality among these workers.

Degraded plastic waste can directly affect humans through direct consumption (i.e. in tap water), indirect consumption (by eating plants and animals), and disruption of various hormonal mechanisms. [12] As of 2019, 368 million tonnes of plastic is produced each year; 51% in Asia, where China is the world's largest producer. [13]
English: :Primary plastic waste generation by polymer Global primary plastic waste generation by polymer type, measured in tonnes per year. Polymer types are as follows: LDPE (Low-density polyethylene); HDPE (High-density polyethylene); PP (Polypropylene); PS (Polystyrene); PVC (Polyvinyl chloride); PET (Polyethylene terephthalate); PUT (Polyurethanes); and PP&A fibres (Polyphthalamide fibres).
Vinyon is a synthetic fiber made from polyvinyl chloride. In some countries other than the United States, vinyon fibers are referred to as polyvinyl chloride fibers. It can bind non-woven fibers and fabrics. It was invented in 1939. It has the same health problems associated with chlorinated polymers.
Materials containing polyvinyl chloride (PVC), polycarbonate, polypropylene, and acrylic, can degrade overtime releasing microplastics. [90] During the construction process single use plastic containers and wrappers are discarded adding to plastic waste . [ 93 ]
