The invented mixture contains (a) from 10 to 65 percent by weight of a resin being selected from a group comprising (i) polyphenylene ether resin, (ii) styrene resin and (iii) a mixture thereof containing 2 to 98 percent by weight of styrene resin, based on the total amount of polyphenylene ether resin and styrene resin, (b) from 30 to 75 percent by weight of propylene polymer grafted with styrene and containing 5 to 70 percent by weight of styrene monomer, and (c) from 1 to 15 percent by weight of one or more monoalkenyl aromatic hydrocarbon-conjugated diene block copolymers, hydrogenated products thereof or mixtures thereof, whereby the total amount of (a) + (b) + (c) is 100 percent by weight and the grafted propylene polymeric material is prepared from propylene polymeric material, having pore ratio at least 0.07, whereby more than 40 percent of pores have diameter greater than 1 micrometer, surface area is at least 0.1 me2/g and average diameter ranges from 0.4 to 7 mm.
