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