Monte Carlo simulations are performed to determine the equation of state of star polymers which are modeled as a collection of freelyhyphen; jointed hard spheres with a central bead that has arms of equal length protruding from it. Threehyphen; and fourhyphen;arm stars are considered with three and five beads per arm, respectively. The generalizedhyphen;Flory dimer theory is extended to star and branched molecules. The theoryrsquo;s predictions for the compressibility factor are in good agreement with the simulation data for the model star polymers.
