Blends continued poly methyl methacrylate

SBM) as a compatibilizer. As a result of the particular thermodynamic interaction between the relevant blocks and the blend components, a discontinuous and nanoscale distribution of the elastomer at the interface, the so-called raspberry morphology, is observed (Fig. 15). Similar morphologies have also been observed when using triblock terpolymers with hydrogenated middle blocks (polystyrene-W<9ck-poly(ethylene-C0-butylene)-Wock-poly(methyl methacrylate), SEBM). It is this discontinuous interfacial coverage by the elastomer as compared to a continuous layer which allows one to minimize the loss in modulus and to ensure toughening of the PPE/SAN blend [69],... 

Conductive polyaniline (PANI) formed the core of the five-component continuous system that also included high-density polyethylene (HOPE), polystyrene (PS), poly(methyl methacrylate) (PMMA), and poly(vinylidene fluoride) (PVDF) along with PS-co-PMMA copolymer. Figure 1.10 shows the SEM micrographs of PANI network in PS/PMMA/PVDF/PANI and PS/PS-co-PMMA/PMMA/PVDF/PANI blends after extraction of all phases by DMF followed by freeze drying. 

The incompatibility of natural rubber/poly(methyl methacrylate) blends was also confirmed in solid form using scanning electron microscopy (Figure 13.4). For the solid natural rubber/poly(methyl methacrylate) blended films prepared by solution mixing and casting methods, the low level of the poly(methyl methacrylate) phase was found to be dispersed as domains in the continuous natural rubber matrix. The increasing amount of poly(methyl methacrylate)... 

PALS was employed to study the free volume parameters of the binodal and spinodal temperature regimes of poly(a-methyl styrene-acrylonitrile) (50/50 by mole) with a methyl methacrylate-methyl acrylate (95/5 by mole) copolymer [399]. The blend exhibited lest behavior and continuous and step changes were noted at the lest for the binodal and spinodal separation, respectively. The phase separation temperature from PALS showed good agreement with more conventional studies (e.g., TEM, DSC).
