  2. Polystyrene - Wikipedia

    en.wikipedia.org/wiki/Polystyrene

    It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. [6] Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year. [7] Polystyrene is naturally transparent, but can be colored

  3. Styrene - Wikipedia

    en.wikipedia.org/wiki/Styrene

    As the difference in boiling points between the two compounds is only 9 °C at ambient pressure this necessitates the use of a series of distillation columns. This is energy intensive and is further complicated by the tendency of styrene to undergo thermally induced polymerisation into polystyrene, [ 22 ] requiring the continuous addition of ...

    en.wikipedia.org/wiki/Boiling_point

    Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor.

  9. PEDOT:PSS - Wikipedia

    en.wikipedia.org/wiki/PEDOT:PSS

    Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is a composite material where PEDOT (the conductive polymer) provides electrical conductivity, and PSS (polystyrene sulfonate) acts as a counter-ion to balance the charge and improve the water solubility and processability of PEDOT.
