A simple, generalized equation of state has been developed for molten polymers. The equation yielded calculated pressure–volume–temperature data that deviated by 1% or less from experimentally determined data. The use of the equation requires only that the polymer's glass temperature and density at 25°C and 1 atm be known. Polymer glass temperatures can also be estimated with the equation.
