Actually Styrofoam is a Dow Chemical registered trade mark for foam insulation and does not refer to all polystyrene so that term is misused. Polystyrene comes in small bead format and then is expanded into shapes like coffee cups, clam shell container at fast food outlets etc. There are also hard polystyrene products, like disposable cutlery, plastic containers like yogurt etc. electronic housing for TVs etc. It can come in clear form too.
The white foam polystyrene can be painted with acrylic paint, but the second you use a solvent based paint on it, it will dissolve.

Why was methanol an appropriate solvent to precipitate polystyrene?
Methanol is used to force polystyrene OUT of solution. So the simple answer is: you can't. But, there is probably an extreme temperature or pressure that allows polystyrene to remain in solution with methanol present.
Is br2 polar or non polar?

Is C10H8 polar or non polar?
Is NH4Cl polar or non polor
Is oil polar or non polar?

Is styrofoam polar or nonpolar?
Thermoplastic is a term that refers to a substance turning into plastic when exposed to extreme temperatures. This would make Styrofoam thermoplastic.
Is corn starch polar or nonpolar?
Both polystyrene and cornstarch are made of polymers, which are long-chain molecules that have a basic repeating unit. Some polymers are polar (such as cornstarch), while others are non-polar (such as polystyrene). The polar parts of cornstarch are hydroxy (--OH) groups that hang off the main chain. These hydroxy groups interact with water molecules to form hydrogen bonds, and as a result, cornstarch is soluble in water.-Journal of Chemical Education According to this, cornstarch is polar and the source seems pretty credible was the Google entry right under this one so way to look it up!
Is br2 polar or non polar?

Is i2 polar or non-polar?
I2 is non-polar
Will polystyrene dissolve sugar?
No, I don't suppose, because Polystyrene is a not a good solvent for polar compounds like sugar, itself being totally nonpolar.
Why does thermocol dissolve in benzene?
Thermocol is another name for polystyrene (PS), which is a type of plastic. Benzene is an industrial solvent, and it's primary use is to make styrene. The chemical structure of benzene, a non-polar organic hydrocarbon solvent, and of PS is such that benzene will dissolve styrene and polystyrene.
Is charcoal polar or non polar?
