    Chemical Properties of Polystyrene

    I need about 5-6, along with a short description of each.
    It'd be helpful if you also listed the sources from where you got them from, thanks.

    +Rep, need this before the end of today.

    1) Polystyrene is chemically nonreactive and hence, used to make containers for other chemicals, solvents and even food items. The transformation of carbon-carbon double bonds into less reactive single bonds in polystyrene, is the main reason for its chemical stability.
    2) Polystyrene is soluble in solvents that contain acetone, such as most aerosol paint sprays and cyanoacrylate glues.
    3) Polystyrene is flexible and can be made into moldable solid or thick viscous solids. This is mainly because of the Van der Waal's forces of attraction, that exist between the long hydrocarbon chains. However, when heat is applied, the chains can slide over each other. This property of intermolecular weakness along with the intramolecular strength, due to the strong hydrocarbon backbone, allows polystyrene to be flexible and stretchable.
    4) Polystyrene is actually an aromatic polymer that is made from the monomer styrene. It is a long hydrocarbon chain that has a phenyl group attached to every carbon atom. Styrene is an aromatic monomer, commercially manufactured from petroleum. Polystyrene is a vinyl polymer, manufactured from the styrene monomer by free radical vinyl polymerization. (not sure if this fits..)

    Tried wikipedia, couldn't find anything new.. You might want to recheck tho, just gave it a quick read. And I'm not sure on the "short" descriptions.
