Scaling near the θ point for isolated polymers in solution -: art. no. 032801

Recently questions have been raised as to the conclusions that can be drawn from currently proposed scaling theory for a single polymer in various types of solution in two and three dimensions. Here we summarize the crossover theory predicted for low dimensions and clarify the scaling arguments that relate thermal exponents for quantities on approaching the theta point from low temperatures to those associated with the asymptotics in polymer length at the theta point itself.
