The intrinsic viscosity of polystyrene in cyclohexane is measured as a function of molecular weight at the critical temperature, 32.9°C. The results are plotted in the form of [r/] 1/3 versus N 1/3 (I-r/] = intrinsic viscosity, N = number of links in a polymer molecule). The scaling law for the collapsed state in the form of R ~ N 1/3 (R -- end-to-end distance) seems to have been obeyed.
