“…When we approach the 0 temperature of the solvent N , tends to infinity (the chain consists of one only blob as predicted by thermal blob theory). Plotting log[v] versus logM (MHS representation) for many polymer-solvent systems we observe, as has already been pointed out by different authors, that the power law between [17] and Mbegins above a certain molecular weight M,. Below M , we observe a crossover region in which the exponent a continuously decreases.…”
