Polystyrene (PS) is one of synthetic polymers which was used in various applications. In this work, polystyrene was synthetized by polymerization of styrene in the presence of benzoyl peroxide (BPO) inisiator at 85 degrees C. Polystyrene was approved by analysis of functional groups with FTIR. Polym...
