摘要：
In this paper we report studies on poly(N-vinylcarbazole) (PNVK) in binary mixtures of THF (1) and poly(ethylene glycol) (2) obtained by viscometry and laser light scattering measurements. From these data, total and preferential solvation parameters were calculated over the whole binary mixture composition range studied. We have not found any inversion in the solvation. Inter- and intra-molecular interactions, Kθ and B, were calculated using the Stockmayer-Fixman equation. Finally, we found that the compatibility between PNVK and PEG increases linearly as PEG molar mass increases. © 1990.
