Polymers are constructed from relatively small molecular fragments known as monomers that are joined together. Wool, cotton, silk, wood and leather are examples of natural polymers that have been known and used since ancient times.

Some materials have excellent stability, such as fluoropolymers, polyimides, silicones and certain acrylate polymers. However, global polymer production is dominated by a range of commodity plastics which account for the majority of plastic waste. LG Chem - Global sales: $17.8 billion. LG Chemical, is the largest Korean chemical company, headquartered in Seoul, South Korea. It is a major manufacturer of petrochemicals, polyolefins, polyvinyl chloride, synthetic rubbers and specialty polymers. During the early days of polymer sciences and engineering, almost all materials were based exclusively upon chemically modified biopolymers. 1, 2 Among polymers, sugar‐based cellulose, which is the major component of biomass, wood, and cotton, represents the most abundant organic compound produced by living organisms.

Chemlon PA 6, PA 66 Chem Polymer Natural Rubber. Natural rubber is an addition polymer that is obtained as a milky white fluid known as latex from a tropical rubber tree. Natural rubber is from the monomer isoprene (2-methyl-1,3-butadiene), which is a conjugated diene hydrocarbon as mentioned above. In natural rubber, most of the double fonds formed in the polymer chain have Polymer. En polymer er et makromolekyle, der sammensat af mange ens byggestene. Plast tilhører familien af polymere materialer.
