The aim of this study was to develop the recycling methode of alloyed recycling plastics. The compatibilizers have been used to improve the physical properties of recycling plastics. Eethylene propylene rubber(EPR), ethylene propylene diene monomer(EPDM), styrene ethylene butylene styrene block copolymer(SEBS), maleic anhydride modified styrene ethylene butylene styrene block copolymer(SEBS-MA) and styrene butadiene styrene block copolymer(SBS) were singled out as compatibilizers. In this study, the physical properties such as impact and tensile strength have improved above 20% by using the compatibilizers.
