Thiol with a blue highlighted sulfhydryl group. In organic chemistry, a thiol ( pron.: / ˈ θ aɪ ˌ ɔː l / , / ˈ θ aɪ ˌ ɒ l / ) [ 1 ] is an organosulfur compound that contains a carbon-bonded sulfhydryl (–C–SH or R–SH) group (where R represents an alkane, alkene, or other carbon-containing group of atoms). Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl group of an alcohol), and the word is a portmanteau of "thio" + "alcohol", with the first word deriving from Greek θεῖον ("thion") = "sulfur". [ note 1 ] The –SH functional group itself is referred to as either a thiol group or a sulfhydryl group .
In chemistry, a carbonate is a salt of carbonic acid , characterized by the presence of the carbonate ion , CO 2− 3 . The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group C(=O)(O–) 2 .
The chemical structure of Polycarbonate In this Kinetic Energy Weapon test, a seven gram Lexan projectile was fired from a light gas gun at a velocity of 23,000 feet per second (7,000 meters per second or 15,682 miles per hour) at a cast aluminum block.
Polycarbonates ( PC ), known by the trademarked names Lexan , Makrolon, Makroclear and others, are a particular group of thermoplastic polymers .
Polysulfone repeating unit. Polysulfone describes a family of thermoplastic polymers.
Polystyrene is an inexpensive and hard plastic , and probably only polyethylene is more common in your everyday life.
Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene . These materials have good abrasion resistance and good aging stability when protected by additives.
Acrylic acid ( IUPAC : prop-2-enoic acid ) is an organic compound with the formula CH 2 =CHCO 2 H. It is the simplest unsaturated carboxylic acid , consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell.
Poly(acrylic acid) ( PAA or Carbomer ) is generic name for synthetic high molecular weight polymers of acrylic acid .
Acrylonitrile is a chemical compound with the formula C 3 H 3 N .
The chemical structure of the polyacrylonitrile repeat unit.
Vinyl alcohol , also called ethenol (IUPAC name), is an alcohol . It is not to be confused with the drinking alcohol, ethanol .
Polyvinyl alcohol ( PVOH , PVA , or PVAl ) is a water - soluble synthetic polymer (not to be confused with polyvinyl acetate , a popular wood glue).
Polypropylene (PP) , also known as polypropene , is a thermoplastic polymer used in a wide variety of applications including packaging and labeling , textiles (e.g., ropes , thermal underwear and carpets), stationery , plastic parts and reusable containers of various types, laboratory equipment, loudspeakers , automotive components, and polymer banknotes .
