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 peanut butter polar or nonpolar?
nonpolar. The fat molecules in peanut butter are nonpolar, that is why peanut butter doesn't evenly mix with water, a polar substance.
How do you explain the phrase like dissolves like in terms of polar and nonpolar substances?
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
