Films of blends of poly(vinylidene fluoride) (PVDF) with isotactic and syndiotactic poly(methyl methacrylate) (i‐PMMA and s‐PMMA), obtained by casting tetrahydrofuran (THF) and dimethyl sulphoxide (DMSO) solutions onto BaF 2 windows, have been investigated by means of FTIR‐microspectroscopy (FTIR‐M), optical microscopy and differential scanning calorimetry (DSC). The study of the effect of the PMMA tacticity on the intermolecular interaction between the two components, as well as on the structure, morphology and thermal behaviour of these blends, is the object of this paper. On the basis of the major shift of the carbonyl band of i‐PMMA in the mixtures, the occurrence of stronger interactions for PVDF/i‐PMMA compared with PVDF/s‐PMMA blends can be suggested. © 1998 SCI.
