Synthesis and characterization of polymeric blends based on polysulfone for special applications

In this paper, synthesis and characterization of new polymeric blends are presented. For copolymerization, the following components: N-vinyl-2-pyrrolidone (NVP), bisphenol A polysulfone (PSU) and bisphenol A glycerolate diacrylate (BPA-A) were used. 2,2-dimethoxy-2-phenyloacetophenone was applied as a photoinitiator. In this method, five polymeric blends with different amounts of PSU were synthesized. Their hardness was investigated using the Shore method. The effect of polysulfone amount on their mechanical and thermal properties was analyzing by means of attenuated total reflectance Fourier-transform infrared spectroscopy (ATR/FT-IR) as well as thermogravimetry and differential thermogravimetry (TG/DTG)
