    Abstract: 0-50 wt.% of polyethylene; 50-95 wt.% of polystyrene; 0.5-20 wt.% of polystyrene-polybutadiene block copolymer; 0.1-10 wt.% of maleic acid anhydride; and 0-1 wt.% of radical initiator. Pref. the polyethylene is LLDPE, LDPE or HDPE; the polystyrene-polybutadiene copolymer comprises 10-90 wt.% of styrene monomer and 10-90 wt.% of butadiene monomer; the maleic acid anhydride derivs. are acryl amide or methacryl amide. The obtd. compsn. can be melt-extracted at 175-240≦̸C and melt-injection molded at 210-250≦̸C, and the molding product has very improved mechanical properties.
