The styrene monomer (from which polystyrene is made) is a cancer suspect agent. [109] Styrene is "generally found in such low levels in consumer products that risks aren't substantial". [110] Polystyrene which is used for food contact may not contain more than 1% (0.5% for fatty foods) of styrene by weight. [111]

Residents near Cleves are being urged to leave their homes Tuesday afternoon because a rail car is leaking styrene. What to know about the chemical.
Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")
Product trade names include Novodur®, Terluran®, and Lustran (ABS); Terlux® (MABS); and Luran® (acrylonitrile styrene acrylate). [3] Styrene-butadiene block copolymer (SBC) is a thermoplastic resin that is transparent and impact-resistant. It is used to provide a high optical appearance and is mostly found in food and display packaging.
