PMMA/PVC/THF ternary systems were studied by viscometry and laser ligh
t scattering. The results obtained show that the compatibility of the
polymer pair PMMA/PVC in THF depends not only on the molar masses of t
he samples but also on the concentration of the PVC. It has been found
that both the unperturbed dimensions, K-0, and the B parameter vary c
onsiderably with PVC concentration. (C) 1998 Elsevier Science Ltd. All
