In nkrile reactions or packaging film, Polymeric Acrylonitrile spurs new R&D ideas. This Du Pont polymer is both an intermediate and a resin. Polymeric acrylonitrilethe intermediate: takes part in many nitrile reactions, converting to amides, carboxy groups, esters, and amines. It can be hydrolyzed to an anionic, water-soluble polymer which will coagulate particles or increase the viscosity of water. Polymeric acrylonitrilethe resin: can be cast from a solvent and biaxially oriented to produce a transparent, heat-resistant film which is impermeable to oxygen and other gases, suggesting its utility as a protective food wrap* This strong, durable film is also resistant to acids, ultraviolet light, brine and most common solvents. Other facts about polymeric acrylonitrile: • A white powder, stable to 150°C. • Soluble in several polar organic solvents and aqueous salt solutions. • Two grades available: Type A-Homopolymer, Molecular Wt.-150,000 Type A-7-Copolymer with 6% methyl acrylate, Molecular Wt-100,000 • Available in commercial quantities.
