In the current work, a series of poly(sodium acrylate)-co-acrylamide (polyNaA-co-AAm/pectin and polyNaA-co-AAm/bentonite) superabsorbent composites were prepared using pectin, bentonite, acrylamide and acrylic acid (AA) in the presence of N,N-methylenebisacrylamide (MBAAm) as cross-linker and a mixture of ammonium persulfate and TEMED as initiator. The structure and sorption capacity of the developed composites were characterized by Fourier transform infrared spectroscopy (FTIR), voltammetry and UV-visible spectro...

In this paper, a PVC filled with a biodegradable polymer, such as polyhydroxybutyrate, was investigated. Polyhydroxybutyrate is a natural biopolymer, but its use limits its high cost. These polymeric composites were obtained by rolling. Thermal and thermomechanical properties of polymer composites based on PVC containing various amounts of polyhydroxybutyrate are studied. It has been determined by differential scanning calorimetry method that the glass transition temperature of PVC decreases with increasing percen...
