The mixing state of poly(vinylidene fluoride) (PVDF) and two amorphous polymers,poly(methyl methacrylate) (PMMA) and poly(isopropyl methacrylate) (PiPMA) were investigated from the viewpoint of crystallization dynamics using simultaneous DSC-FTIR method. The crystallization rate (R*) and the growth rate of trans-gauche-trans-gauche’ (TGTG’) conformation (Rc*) depended on both the blend content (ϕ) and the crystallization temperature for PVDF/PMMA. The temperature and ϕ dependency of R* and Rc* were almost the same for PVDF/PMMA. However, R* and Rc* depended scarcely on f for PVDF/PiPMA, and the temperature dependency of R* differed from that of Rc* for PVDF/PiPMA. These results showed that PVDF and PMMA were miscible on molecular level, and that PVDF/PiPMA was immiscible and the concentration fluctuation existed in the PVDF-rich phase.
