ABS stands for Acrylonitrile Butadiene Styrene. Acrylonitrile is an organic compound with the formula CH 2 CHCN. Acrylonitrile / Butadiene (NBR) NBR, Buna-N, and nitrile all represent the same elastomer based on a butadiene and acrylonitrile copolymer. % Synonym: 1,3-Butadiene-acrylonitrile copolymer, Acrylonitrile-1,3-butadiene copolymer, Acrylonitrile-butadiene copolymer, Poly(acrylonitrile-butadiene) CAS Number 9003-18-3. 91628-89-6. Prop-2-ene(~15~N)nitrile. Styrene-Acrylonitrile Copolymer. 107-13-1, assigned by the Chemical Abstracts Service. Acrylonitrile butadiene rubber (NBR), usually shortened to nitrile, is a unique elastomer. It can be produced by free-radical emulsion polymerization of butadiene with 15 to 45 percent acylonitrile either hot (hot rubber) or cold (cold rubber): It is a colorless volatile liquid although commercial samples can be yellow due to impurities. Acrylonitrile. NBR - Butadiene Nitrile Rubber Properties. Na Han, Xiyin Gao, Rong Zhang, Xingxiang Zhang, Structures and properties of thermoregulated acrylonitrile–methyl acrylate sheet containing microphase change materials, Polymer Composites, 10.1002/pc.22453, 34, 5, (641-649), (2013). The three most important comonomers are styrene, butadiene, and methyl acrylate. Acrylonitrile Butadiene Styrene (ABS) plastics are polymers made by the polymerization of styrene and acrylonitrile. About 30 to 85 percent by weight of the copolymer is acrylonitrile and about 15 percent or more is butadiene and/or methyl acrylate. NACRES NA.23 ABS is an impact-resistant engineering thermoplastic & amorphous polymer. SAN copolymers have been available since the 1940s and while their increased toughness over polystyrene made them suitable for many applications, their limitations led to the introduction of a rubber, butadiene, as a third monomer, producing the range of materials popularly referred to as ABS plastics. Poly(acrylonitrile-co-butadiene) acrylonitrile 37-39 wt. The chemical structure of Acrylonitrile is: CH2=CH-CN Ammoxidation Process Acrylonitrile is manufactured by combining propylene, It has a pungent odor of garlic or onions. Acrylonitrile-15N. Acrylonitrile polymers (also called nitriles) are copolymers of acrylonitrile and various other monomers. Acrylonitrile is a clear, colorless liquid with a slightly pungent odor. DTXSID00745782. Acrylonitrile-15N, >=98 atom % 15N, >=99% (CP), contains hydroquinone as stabilizer ABS is made up of three monomers: acrylonitrile, butadiene and styrene: Acrylonitrile: It is a synthetic monomer produced from propylene and ammonia. POLYMER CLASS: Polynitrile: COMMON NAMES: Poly(acrylonitrile) STRUCTURE BASED NAME: Poly(1-cyanoethylene), Poly(cyanoethylene), Poly(2-propenenitrile) ACRONYMS Nitrile is inherently resistant to hydraulic fluids, lubricating oils, transmission fluids and other non-polar petroleum based products due to the polar structure … This component contributes to ABS chemical resistance & heat stability Linear Formula [CH 2 CH(CN)] x (CH 2 CH=CHCH 2) y. MDL number MFCD00133994. Acrylonitrile multipolymers containging indene, methyl methacrylate, and α‐methyl methacrylate are used as PVC modifiers for HDT and processability improvement. In terms of its molecular structure, it consists of a vinyl group linked to a nitrile.It is an important monomer for the manufacture of useful plastics such as polyacrylonitrile. Acrylonitrile is the main monomer of synthetic fibres commonly called acrylics which are defined, according to the Federal Trade Commission of the United States, as manufactured fibres in which the fibre-forming substance is any long-chain synthetic polymer composed of at least 85% by weight of acrylonitrile units (Guillen, 1987). Copolymers of acrylonitrile and methly acrylate and terpolymers of acrylonitrile, styrene, and methyl methacrylate are used as barrier polymers.
