Household items made of various types of plastic

A *plastic* material is any of a wide range of synthetic or semi-synthetic
organic solids that are moldable. Plastics are typically organic polymers
of high molecular mass, but they often contain other substances. They are
usually synthetic, most commonly derived from petrochemicals, but many are
partially natural.^[1]

*Composition[edit]*

Most plastics contain organic polymers. The vast majority of these polymers
are based on chains of carbon atoms alone or with oxygen, sulfur, or
nitrogen as well. The backbone is that part of the chain on the main "path"
linking a large number of repeat units together. To customize the
properties of a plastic, different molecular groups "hang" from the
backbone (usually they are "hung" as part of the monomers before
