Monte Carlo simulations of randomly branched polymers with annealed and quenched branching structures

We present three-dimensional off-lattice Monte Carlo simulations on randomly branched polymers with annealed and quenched branching structures when monomers interact with each other through excluded volume interactions. The values of the critical exponent for the mean-square radius of gyration are estimated on the basis of scaling analysis as νₐ=0.49±{}0.01 (annealed) and νq=0.45±{}0.01 (quenched), which suggest that annealed and quenched randomly branched polymers belong to different universality classes. We further confirm the existence of a scaling parameter that was deduced earlier by the perturbation theory and the Flory-type argument. {} 1996 The American Physical Society.
