Corrections to scaling in multicomponent polymer solutions

We calculate the correction-to-scaling exponent ωT that characterizes the approach to the scaling limit in multicomponent polymer solutions. A direct Monte Carlo determination of ωT in a system of interacting self-avoiding walks gives ωT = 0.415 ± 0.020. A field-theory analysis based on five- and six-loop perturbative series leads to ωT = 0.41 ± 0.04. We also verify the renormalization-group predictions for the scaling behavior close to the idealmixing point. The behavior of dilute or semidilute solutions of long polymers have been investigated at length by using the renormalization group, 1–3 which has explained the scaling behavior observed in these systems and has provided quantitative predictions that become exact when the degree of polymerization becomes infinite. Most of the work has been devoted to binary
