Thermoplastische Formmasse

摘要

The invention relates to a molding material comprising 45 to 95 wt. % styrene and 1.1-diphenylethylene copolymer(S/DPE copolymer) with 37 to 85 wt. % polymerized styrene units and 15 to 63 wt. % polymerized 1.1-diphenylethylene units or a styrene-S/DPE double block copolymer whose S/DPE block has the above-mentioned composition. The inventive molding material also contains 5 to 55 wt. % of a rubber-elastic microsuspension graft polymer consisting of particles with a diameter d50 of 30 mu m or less with a rubber-elastic graft core consisting of units of one or several C2-36-alkyl-acrylic esters with a glass transmission temperature Tg lower than -10 DEG C and a graft shell made of at least 50 wt. % polymerized styrene units.
