摘要
The phase behavior of lightly sulfonated poly(phenylene oxide) (SPPO)/poly(styrene-co-3-vinylpyridine) (PSVP) blend was investigated by DSC. It was found that the acid-base interaction between the sulfonic group of SPPO and the pyridine ring of PSVP improves miscibility effectively. This acid-base interaction was demonstrated by viscometry, IR spectra and C-1-NMR spectra. (C) 2000 Elsevier Science Ltd. All rights reserved.
