P-METHYLSTYRENE is a clear colorless liquid with an aromatic odor. Usually shipped with an inhibitor such as tert-butyl catechol added May polymerize if contaminated or subjected to heat. If polymerization takes place inside a closed container, the container may rupture violently. Vapors irritate the mucous membranes. Less dense than water and insoluble in water. Hence floats on water. Used in making plastics, especially as a monomer for polyesters.
