Polystyrene (abbreviated as PS) refers to the polymer synthesized by free radical addition polymerization of styrene monomer, with the chemical formula of (C8H8) n. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100 ℃, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.
