Wertheim's first order thermodynamic perturbation theory (TPT1) [1] [2] [3] [4] [5] can be expressed as:
where is the equation of state of the monomer system and m is the number of monomers in the chains.
For example, in the study of the flexible hard sphere chain model one can use the Carnahan-Starling equation of state for , leading to
