High impact thermoplastic resin composition

A high-impact thermoplastic resin composition comprising:

• (A) 5 to 95 parts by weight of a thermoplastic elastomer composition comprising a partially or completely crosslinked rubbery polymer and a polyolefinic resin and/or a polystyrene-based resin and optionally a second polyolefinic resin;
• wherein organic peroxides are used as a crosslinking agent,
• wherein said rubbery polymer is selected from the group consisting of
• 1) a rubbery polymer being an ethylene-α-olefin copolymer or an ethylene-α-olefin copolymer with a conjugated diene and/or a non-conjugated diene used as a copolymer component wherein the amount of said conjugated diene and/or non-conjugated diene is not more than 50% by weight based on said copolymer.
• 2) a rubbery polymer being a hydrogenated diene polymer obtained by hydrogenating at least 50% of the double bond of the diene;
• and
• 3) a rubbery polymer being a hydrogenated aromatic vinyl/conjugated diene block or random copolymer obtained by hydrogenating at least 90% of the double bond based on said conjugated diene moiety,
• (B) 95 to 5 parts by weight of at least one thermoplastic resin selected from the group consisting of polystyrene-based resins, polyamide-based resins, polyurethane-based resins, polycarbonate-based resins, polyphenylene ether-based resins, polyester-based resins, acrylic resins, polyacetal-based resins and polyphenylene sulfide-based resins;
• the total of the components (A) and (B) being 100 parts by weight, wherein the amount of the rubbery polymer in the composition is 1 to 40% by weight, wherein the wt % of the rubbery polymer is based on the total weight of components (A) and (B) and, if present, a compatibilizing agent (C);
• and wherein the high-impact thermoplastic resin composition has a Shore D hardness of at least 50.
