The compositions and structures of interpolymer complexes formed by mi
xing phenoxy resin (PHEB) and poly (4-vinylpyridine) (P4VPy) in chloro
form have been studied by means of elemental analysis, DSC, FTIR, UV a
nd XPS, In the meantime, the corresponding blends prepared have been c
haracterized and compared. The results show that compositions of the c
omplexes were identical with the ratio of equimolar interactive units.
All blends were miscible and their compositions were related to the f
eed ratios. Based on the experimental results, process of formation of
the complex is depicted.
