Abstract
Impact resistant thermoplastic molding materials containing a styrene polymer modified with rubber to be impact resistant, a hydrogenated styrene containing block copolymer and a polyphenylene ether as well as optional additives in which 50 to 98 percent by weight of the particles of the flexible component of the impact resistant styrene polymer have an average particle diameter of equal to or less than 1.0 micron and 2 to 50 percent by weight of the particles of the flexible have an average particle diameter of equal to or greater than 2 microns.
