Sažetak
The efficiency of graft copolymer EPDM-g-PS on miscibility in SAN/EPDM blends has been studied. SAN/EPDM blends have poor physical and mechanical properties caused by their low miscibility. All studied samples were prepared by casting films from chloroform solution. The first seria of samples contains SAN and EPDM in ratio 95/5 ; 90/10 ; 85/15 ; 80/20 and in second seria 5 mass % of graft copolymer EPDM-g-PS was added. Graft copolymer EPDM-g-PS was synthesized in heptane with benzoyl peroxide as initiator. Mechanical properties of prepared samples: tensile strength and elastic moduls (at three different rates of extension) were determinated. EPDM-g-PS, SAN and EPDM were characterized by IR spectrophotometry. The obtained results show that tensile strength increases with the rate of extension. From lower values of tensile strength it can be seen that graft copolymer EPDM-g-PS significantly decreases hardness and improves elasticity. From that results it is obvious that adding of graft copolymer EPDM-g-PS into SAN/EPDM blends has the significant influence on their properties and miscibility.
