Abstract:Sulfonated polystyrene (SPS) is a polyelectrolyte solid that is widely used in many applications. In this study, the sulfonation reaction of food packages polystyrene (PS) waste was done using sulfuric acid as a sulfonation agent, with the variation of concentration and times. The degree of sulphonation was determined. Composite from SPS and two types of fillers (carbon black and Nano silica) were synthesized, and new IPNs between SPS and phenolic resin type novolac was prepared. The characterization of the su… Show more
