Polycarbonate
Made by reacting bisphenol and phosgene, or by reacting a polyphenol with methylene chloride and phosgene. The monomer may be OC6H4C(CH3)2C6H4OC:O. The molecular structure is in double-linked zigzag chains that give high rigidity. The resin is thermoplastic. It is crystalline with rhombic crystals.
Polycarbonate is a linear, low-crystalline, transparent, high-molecular-weight plastic. It is generally considered to be the toughest of all plastic. In thin sections, up to about 3/16 in (0.478 cm), its impact strength is as high as 16 ft • lb (24 kg • m). In addition, polycarbonate is one of the hardest plastics. It also had good strength and rigidity, and, because of its high modulus of elasticity, is resistance to creep. These properties, along with its excellent electrical resistivity, are maintained over a temperature range of about —275 to 250°F (—170 to 121°C). It has negligible moisture absorption, but it also has poor solvent resistance, and, in a stressed condition, will craze or crack when exposed to some chemicals. It is generally unaffected by greases, oils, and acids. Polycarbonate plastics are easily processed by extrusion, by injection, blow, and rotational molding, and by vacuum forming.
They have very low and uniform mold shrinkage. With a white light transmission of almost 90% and high impact resistance, they are good glazing materials. They have more than 30 times the impact resistance of safety glass. Other typical applications are safety shields and lenses. Besides glazing, polycarbonate’s high impact strength makes it useful for air-conditioner housings, filter bowls, portable tool housings, marine propellers, and housings for small appliances and food-dispensing machines.
Applications:
· Insulating bolts and nuts
· Valves keyboard cases
· Electric tool housings
· Medical devices
· Cocks
· Cellular phone housings

Acrylonitrile-Styrene
Also called vinyl cyanide and propene nitrile. A liquid of the composition CH2:CHCN, boiling at 78°C, used in insecticides and for producing plastic and other chemicals. It is made by the addition of hydrocyanic acid to acetylene, by using propylene as the starter and reacting with ammonia, or from petroleum. Acrylonitrile fiber, originally developed in Germany as a textile staple fiber and as a monofilament for screens and weaving, and known as Redon, has good dimensional stability and high dielectric strength, and is resistant to water and to solvents. The polymerized acrylonitrile has a molecular structure that can be oriented by drawing to give fibers of high strength. Orlon, of Du Pont, is a polymerized acrylonitrile fiber. It is nearly as strong as nylon, and has a softer feel. It can be crimped to facilitate spinning with wool. It is used for clothing textiles and for filter fabrics. Dynel, of Union carbide Corp., is an acrylonitrile-vinyl chloride copolymer staple fiber. It produces textiles with a warmth and feel like those of wool. It has good strength, is resilient, dyes easily, and is moth proof. Verel, of the Eastman Chemical Products, Inc., is a similar acrylic fiber produced from acrylonitrile and vinylidene chloride, and Creslan, of the American Cyanamid Co., called Exlan in Japan, is an acrylic fiber. Acrilan, of the Chemstrand Corp., is a similar textile fiber, and is an acrylonitrile-vinyl acetate copolymer. Bakelite C-11 is an acrylonitrile-styrene copolymer for injection molding and extruding that produced rigid thermoplastic parts of higher tensile strength than those of the methacrylates, and has good dimensional stability and scratch resistance. Saran F-120, of the Dow Chemical Co., is a similar material.
Zefran, of the Dow Chemical Co., is an acrylonitrile polymerized with vinyl pyrrolidone or other dye-receptive monomer. The fiber has a molecular structure called a nitrile alloy, with a continuous polyacrylonitrile backbone with close-packed hydrophilic groups which hold the dye molecules. It resists heat to 490°F (254°C). Fostacryl, of the Foster Grant Co., Inc., is a crystal-clear styrene-acrylonitrile copolymer used for molding such articles as dinnerware and food containers. Acrylonitrile-styrene copolymers are also combine with alkyl-substituted phenolic resins to produce hard, glossy, flexible coatings. Itaconic acid, or methylene succinic acid, CH2:CCH(COOH)2, is also polymerized with acrylonitrile to produce fibers. When this acid is polymerized with styrene it produces transparent plastics of good optical properties. For jet aircraft tires an extremely wear-resistant rubber is made of acrylonitrile-butadiene with an organometalic catalyst that has alternating groups in the copolymer.
Acrylonitrile reacts with cellulose to form a wide range of resins from soluble eithers useful for textile finishes to tough, resistant materials useful for fibers. It can be reacted directly with cotton to improve the fiber. Krilium, of the Monsanto Co., and Agrilon, of the Borden Chemical Co., are sodium salts of acrylonitrile used as soil conditioners. They are more efficient than peat moss.
