“…It is proved by the peak positions of 3373 and 3173 cm À1 (m(-OH)), 1710 cm À1 (m(C@O)), 1590 cm À1 (m(C@C), the wave number increasing by about 30 cm À1 may be caused by conjugated bond) and 1420 cm À1 (m s (COO À )) [20][21][22][23]. And the weak peak located at 1272 cm À1 is in accordance with the vibration of the C-O-C bond [24][25][26].…”

“…Taking T g for styrene, butyl acrylate, and ethyl acrylate as 100°C, -43°C and -8°C, respectively, 19 the T g calculated from Fox's equation, , is shown in Table 2. 20 Application of this equation assumes a perfect random copolymer and the reaction yield to be the same for each monomer. Nevertheless, it is striking that the Fox equation fails to adequately predict the T g , while the MFFT bar experiments are within 3°C of the DSC measurements.…”

The change of minimum film formation temperature (MFFT) with time was studied utilizing a temperature gradient bar. Fitting the data to a theory which assumed that particles deform due to the action of the polymer-air surface tension, the glass transition temperature, T g , of the latex was predicted. This T g was compared to the value obtained by differential scanning calorimetry (DSC) and good agreement was observed between the two measurements.

“…On the other hand, they are partially compatible only if the resulting blends would have two T gs related to each component, but with different values when compared to the pure polymers [43] . The theoretical T g values can be predicted using the Fox equation [44] :…”

Chitosan/poly(methyl methacrylate-co-butyl methacrylate) (PMMA-co-BMA) blends were prepared via a solution blending method in the presence of formic acid. The compatibility of the bioblends was studied by different methods, such as Fourier transform infrared and Raman spectroscopy, micro-Raman imaging, thermogravimetric analyses, differential scanning calorimetry and scanning electron microscopic analysis. According to the obtained results, it has been concluded that the PMMA-co-BMA/chitosan bioblends are compatible in all the studied compositions. Specific interactions between carbonyl and methyl groups of the PMMAco-BMA structure and methyl, amine and amide groups of chitosan are responsible for the observed compatibility. INTRODUCTIONConcerns about environmental problems such as global warming, pollution of natural resources, renewable energy use and cost of synthetic polymers have motivated an intense research of sustainable polymer systems where at least one component is biodegradable or biobased [1] . The commercial importance of polymers also have increased the need of discover of new materials with specific properties and applications; for this purpose new polymers have been synthesized and chemical modifications in conventional polymers have also been proposed, but these methods are more complicated [2,3] . However, the mixture of two or more polymers, giving rise to a polymer blend, seems to be an economical method to obtain new polymeric materials with desirable properties, without the need of synthesizes specialized polymer systems [4,5] .
