Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the ...
Acrylonitrile is used principally as a monomer to prepare polyacrylonitrile, a homopolymer, or several important copolymers, such as styrene-acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylate (ASA), and other synthetic rubbers such as acrylonitrile butadiene (NBR).
The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...
For example, in the free-radical copolymerization of styrene maleic anhydride copolymer, r 1 = 0.097 and r 2 = 0.001, [11] so that most chains ending in styrene add a maleic anhydride unit, and almost all chains ending in maleic anhydride add a styrene unit. This leads to a predominantly alternating structure.
Acrylonitrile butadiene styrene, a common plastics polymer; Anti-lock braking system, in vehicles; Abs usually refers to: Rectus abdominis muscle ("abdominal muscle" or "abs") of humans and some mammals; Abdominal muscles (colloquial) ABS or Abs may also refer to:
Acrylonitrile butadiene styrene (ABS) is a terpolymer synthesized from styrene and acrylonitrile in the presence of polybutadiene. ABS is a light-weight material that exhibits high impact resistance and mechanical toughness. It poses few risks to human health under normal handling.
It was made into the spun fiber at DuPont in 1942 and marketed under the name of Orlon. Acrylonitrile is commonly employed as a comonomer with styrene, e.g. acrylonitrile, styrene and acrylate plastics. Labelling of items of clothing with acrylic (see acrylic fiber) means the polymer consists of at least 85% acrylonitrile as the monomer. A ...
Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. [1] Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals.
