Acrylonitrile butadiene styrene (ABS) is a common thermoplastic polymer. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The styrene gives the plastic a shiny, impervious surface. The polybutadiene, a rubbery substance, provides toughness even at low temperatures.
