Abstract: | A polymer chain consisting of Nr segments with a repulsive interaction (binary cluster integral βr) and Na ? Nr segments with a stronger, attractive and pairwise saturable interaction (βa), which is at the averaged θ-point N2rβr + N2aβa = 0 deviations from the predictions of the two parameter theory: and A2 ~ δzr > 0 with . It is shown that the deviations from the universal behaviour are due to the existence of an intermediate length scale . |
