چکیده:

Polymer blends represent materials for a large class of industrial products and are the subject of intensive academic research. Blending of chemically different polymers is an important tool in industrial production for tailoring products with optimized material properties. Polystyrene is one of the most widely used thermoplastic materials. Owing to their special property profit, styrene polymers are placed between commodity and specialty polymers. Polystyrene is a brittle thermoplastic material. To overcome the brittleness of polystyrene, the material was modified with by incorporation of polybutadiene. Modified polystyrene consists of a polystyrene matrix with embedded cellular rubber particles. The aim of this work is producing polymer blend of polystyrene/g-ABS through in situ polymerization. In this research styrene monomer, benzoyl peroxide (initiator) and g-ABS are used to obtain polymer blend at 90 °C. The addition of g-ABS increased and improved mechanical properties of polystyrene such as impact strength, elongation at break, HDT, and etc
