摘要：

Blends of poly(vinylidene fluoride) (PVDF) and some poly(vinyl alcohol-co-vinyl acetate) copolymers (PVAAc) with various molecular weights and acetate contents are studied by differential scanning calorimetry. First, two sets of blends of PVDF with two different PVAAc at various concentrations are analysed. Then, 50/50 (wt/wt) blends of each copolymer with PVDF are studied. Even though the glass transitions of both polymers are not observable, the PVDF melting and crystallization data give some indications about these blends: (1) the amorphous phases of both polymers seem to be, in any case, immiscible; (2) the crystallization of PVDF is modified by mixing with the copolymers (PVAAc), the most crystalline of them (with low acetate contents) improving its crystallinity ratio.
