About Polymer Plastic

Shrink-wrap is a material made up of polymer plastic and PVC...

A polymer is the name of any of the many natural and synthetic compounds, which have usual high molecular weight that consist of up to millions of repeating linked units, strung together through chemical bonds. This process of bonding two or more monomers to form a polymer is called polymerization. Monomers are small molecules with low molecular weight.

Monomers can either be identical, or have one or more substituted chemical groups. These differences between monomers change their properties. Some monomers are hydrocarbons such as styrene and ethene, which form polymers that make plastics such as polystyrene and polyethene.

Polymers created from monomers with 2, 3, 4, 5, 8, or 20 monomer units are referred to as dimers, trimers, tetramers, pentamers, octamers, 20-mers, respectively. The number of monomer units can be indicated by an appropriate prefix, such as decamer, for a 10-unit monomer chain.
