In this study, the pure polystyrenes (PS) with different molecular weights (3.5 × 105 and 5.0 × 105) have been modified by the chemical modification with succinic anhydride (SA), maleic anhydride (MA), and phthalic anhydride (PhA). The modified polystyrenes (MPS) have been mixed with the pure PS with the molecular weight of 2.3 × 105 in weight % ratio 90:10, 80:20, and 70:30. Young’s modulus of obtained...
