Bullet-proof glass

Another use of acetone in the chemical industry is for bisphenol A ( ). BPA results form the condensation reaction of acetone and phenol in the presence of an appropriate catalyst. BPA is used in polycarbonate plastics, polyurethanes, and epoxy resins. Polycarbonate plastics are tough and durable and are often used as a glass substitute. Eyeglasses, safety glasses, and varieties of bullet-proof glass are made of polycarbonates. Additional... 

Polycarbonates A group of thermoplastics composed of polymers of carbonate groups. Polycarbonates are used primarily for bullet-proof glass, CDs and cooking wares. 

Lexan is a plastic used to make compact discs, eyeglass lenses, and bullet-proof glass. One of the compounds used to make Lexan is phosgene (COCI2), a poisonous gas. Phosgene is produced by the reaction... 

Polycarbonates are like polyesters, but their carbonyl group is linked to two -OR groups, [0=C(OR)2]. Lexan, for instance, is a polycarbonate prepared from diphenyl carbonate and a diphenol called bisphenol A. Lexan has an unusually high impact strength, making it valuable for use in machinery housings, telephones, bicycle safety helmets, and bullet-proof glass.
