Non-reinforced thermoplastic molding compositions

The invention relates to a thermoplastic moulding material containing the following ingredients in relation to the sum of ingredients A C and optionally D-A, whereby said sum corresponds to 100 wt. %: a) 10-98 wt. % of at least one aromatic polyester as ingredient A; b) 1-50 wt. % of at least one particle-shaped grafted copolymer with a soft phase glass transition temperature of less than 0 DEG C and an average particle size of 50-1000 nm as ingredient B; c) 1-50 wt. % of at least one copolymer consisting of monomers c1) 50-90 wt. % of at least one vinyl aromatic monomer as ingredient C1 and c2) 10-25 wt. % acrylonitrile and/or methylnitrile as ingredient C2, as ingredient C; d) 0-25 wt. % other compatible polymers that can be homogenously mixed with ingredients A and/or C or dispersed therein as ingredient D; e) 0-10 wt. % usual additives such as carbon black, pigments, UV stabilizers, oxidation retarders, lubricating agents and mould-release agents as ingredient E. The invention also relates to moulded parts made of said moulding materials, used in the interiors of motor vehicles, in addition to the use of said moulding materials in the production of moulded parts.
