Acrylonitrile ia-kr9-l6- nl-tr9l, - trel (1893) (propenenitrile, vinyl cyanide) n. (1) A monomer with the structure CH2=CH-CN. It is most useful in copolymers. Its copolymer with butadiene is nitrile rubber, and several copolymers with styrene exist that are tougher than polystyrene. It is also used as a synthetic fiber and as a chemical intermediate. (2) A raw material for the manufacture of synthetic resins and rubbers. It is a liquid at room temperatures, with a bp of 77° C and ftp of 0°C. Kadolph SJ, Langford AL (2001) Textiles.

Polymer Solvent. Sulfolane is a solvent for a variety of polymers, including polyacrylonitrile (PAN), poly(vinyhdene cyanide), poly(vinyl chloride) (PVC), poly(vinyl fluoride), and polysulfones (124—129). Sulfolane solutions of PAN, poly(vinyhdene cyanide), and PVC have been patented for fiber-spinning processes, in which the relatively low solution viscosity, good thermal stabiUty, and comparatively low solvent toxicity of sulfolane are advantageous. Powdered perfluorocarbon copolymers bearing sulfo or carboxy groups have been prepared by precipitation from sulfolane solution with toluene at temperatures below 300°C. Particle sizes of 0.5—100 p.m result. [Pg.70]

New teipolymers of vinyl acetate with ethylene and carbon monoxide have been prepared and their uses as additives to improve the curing and flexibihty of coating resins, eg, nitrocellulose, asphalt, phenoHcs, and polystyrene, have been described (130—132). Vinyl acetate and vinyUdene cyanide form highly alternating copolymers. [Pg.467]

It has been shown52 that under similar conditions reduction of the nitrile groups in cellulose ethyl cyanate and of those in the copolymer of vinylidene cyanide with vinyl acetate, proceed simultaneously in two directions with the formation of aldehyde and amine groups. g+ g ... [Pg.117]

Poly(vinyl acetate) grades that are resistant to hydrolysis are obtained by copolymerization with vinyl stearate and vinyl pivalate (vinyl ester of trimethyl acetic acid), since the saponification rate is reduced by the bulkier side groups. Pure poly(vinyl pivalate) has too high a glass-transition temperature (78°C) for most poly(vinyl ester) applications. Copolymerization with vinylidene cyanide yields a fiber with a feel similar to Cashmere wool. Other copolymers are produced with olefins (see Section 25.2.1.5) and vinyl chloride (see Section 25.7.5.5)... [Pg.904]

Random copolymers based on acrylonitrile and methacrylonitrile with ethyl a-acetoxyacrylate [69] were synthesized by radical copolymerization. The microstructure of the resulting copolymers was characterized by C NMR spectroscopy, and some reactivity ratios could be assessed. In addition, copolymers based on methyl vinylidene cyanide (MVCN) and vinyl acetate [70], styrene [71], or substituted styrene also exhibit interesting dielectric behavior [72]. [Pg.457]

Monomers with electron-rich double bonds produce one-to-one copolymers with monomers having electron-poor double bonds in reaction systems that also contain certain Lewis acids. These latter are halides or alkyl halides of nontransition metal elements, including AlCb, ZnCh, SnCL, BF3, AI(CH2CH3)Cl2, alkyl boron halides, and other compounds. The acceptor monomer generally has a cyano or carbonyl group conjugated to a vinyl double bond. Examples are acrylic and methacrylic acids and their esters, acrylonitrile, vinyl ketones, maleic anydride, fumaric esters, vinylidene cyanide, sulfur dioxide, and carbon monoxide. The variety of donor molecules is large and includes various olefins, styrene, isoprene, vinyl halides and esters, vinylidene halides, and allyl monomers [30]. [Pg.270]
