Abstract

We calculate the correction-to-scaling exponent omega(T) that characterizes the approach to the scaling limit in multicomponent polymer solutions. A direct Monte Carlo determination of omega(T) in a system of interacting self-avoiding walks gives omega(T)=0.415 +/- 0.020. A field-theory analysis based on five- and six-loop perturbative series leads to omega(T)=0.41 +/- 0.04. We also verify the renormalization-group predictions for the scaling behavior close to the ideal-mixing point.
