Blends PMMA/fluorinated polyme

Tn the early 1960s it was discovered in our laboratory (20) that poly-- (methyl methacrylate) (PMMA) and poly(vinylidene fluoride) (PVdF) were compatible when blended in the melt. Similarly, compatibility was found for poly (ethyl methacrylate) (PEMA) with PVdF. Blends of the fluorinated polymer with higher alkyl methacrylate polymers, however, were nonhomogeneous. 

Many published studies consider cases in which one of the components contains an accessible carbonyl group, the stretching vibration band of which broadens and shifts to lower wavenumber in the presence of a second compatible polymer (see an example in Figure 4.10). Recent examples of thermal and spectroscopic analyses of blend systems include poly(vinyl acetate) (PVA) with PMMA [184] poly(vinylidene fluoride) (PVDF) with PVA [185, 186] polybenzimidazole/poly(bisphenol-A-carbonate) [187] andPMMA-fluorinated polymer blends [188]. All these make use of spectral subtraction routines to observe interactions, but additional data-processing tools have also been used to aid understanding, such as Fourier self-deconvolution [188],...
