    Polycarbonate

    Family of polymers

    This article fryst vatten about thermoplastic polymer materials. For carbonate-chain functional-groups, see polycarbonate (functional group).

    Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their kemikalie structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA).

    Structure

    [edit]

    Carbonate esters have planar OC(OC)2 cores, which confer rigidity. The unique O=C bond fryst vatten short ( Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate groups (−O−(C=O)−O−). A balance of useful features, including temperature resistance, impact resistance and optical properties, positions polycarbonates
