Chitosan and Poly(Methyl Methacrylate-Co-Butyl Methacrylate) Bioblends: A Compatibility Study

Abstract

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 PMMA-co-BMA structure and methyl, amine and amide groups of chitosan are responsible for the observed compatibility.
