Polymers
Compounds formed by the joining of smaller, usually repeating, units linked by covalent bonds. These compounds often form large macromolecules (e.g., BIOPOLYMERS; PLASTICS).
Year introduced: was in Cat D & J 1975-1982, was in Cat D only 1963-1974
Fluorocarbon Polymers
Year introduced: 1966
Molecularly Imprinted Polymers
Synthetic polymeric matrices with artificial molecular recognition sites generated by MOLECULAR IMPRINTING TECHNIQUE. It can specifically bind target molecules (e.g., antibodies, enzymes or receptors).
Year introduced: 2021
Stimuli Responsive Polymers
Polymeric materials designed to change properties in response to a stimulus.
Year introduced: 2020
Polypropylenes
Propylene or propene polymers. Thermoplastics that can be extruded into fibers, films or solid forms. They are used as a copolymer in plastics, especially polyethylene. The fibers are used for fabrics, filters and surgical sutures.
Year introduced: 1991(1975)
Polymethacrylic Acids
Poly-2-methylpropenoic acids. Used in the manufacture of methacrylate resins and plastics in the form of pellets and granules, as absorbent for biological materials and as filters; also as biological membranes and as hydrogens. Synonyms: methylacrylate polymer; poly(methylacrylate); acrylic acid methyl ester polymer.
Year introduced: 1981(1975)
Metal-Organic Frameworks
Supramolecular networks that consist of ordered arrangements of organic electron donor linkers (usually ditopic or polytopic organic carboxylates) and metal cations. They can have an extremely high surface area and adjustable pore size that allows for the insertion of other molecules capable of various functions such as catalysis, capture of carbon dioxide, and drug delivery.
Year introduced: 2018
Dendrimers
Tree-like, highly branched, polymeric compounds. They grow three-dimensionally by the addition of shells of branched molecules to a central core. The overall globular shape and presence of cavities gives potential as drug carriers and CONTRAST AGENTS.
Year introduced: 2006
Proanthocyanidins
Dimers and oligomers of flavan-3-ol units (CATECHIN analogs) linked mainly through C4 to C8 bonds to leucoanthocyanidins. They are structurally similar to ANTHOCYANINS but are the result of a different fork in biosynthetic pathways.
Year introduced: 2004
Bisphenol A-Glycidyl Methacrylate
The reaction product of bisphenol A and glycidyl methacrylate that undergoes polymerization when exposed to ultraviolet light or mixed with a catalyst. It is used as a bond implant material and as the resin component of dental sealants and composite restorative materials.
Year introduced: 1993
Polyethylenes
Synthetic thermoplastics that are tough, flexible, inert, and resistant to chemicals and electrical current. They are often used as biocompatible materials for prostheses and implants.

Smart Materials
Materials designed to change properties in response to changes in their environment adopting various predetermined shapes and/or functionalities.
Polylactic Acid-Polyglycolic Acid Copolymer
A co-polymer that consists of varying ratios of polylactic acid and polyglycolic acid. It is used as a matrix for drug delivery and for BONE REGENERATION.
Year introduced: 2019 (1984)
Polyethylene Terephthalates
Polyester polymers formed from terephthalic acid or its esters and ethylene glycol. They can be formed into tapes, films or pulled into fibers that are pressed into meshes or woven into fabrics.
Neoprene
An oil-resistant synthetic rubber made by the polymerization of chloroprene.
