Polymer composition for car body parts, e.g. mud guards or bumpers, shows low deflection in the heat sag test and contains polyamide, syndiotactic polystyrene, styrene copolymer or graft copolymer, and impact modifier

摘要

A polymer composition (I) which is suitable for the production of car body parts shows a deflection of less than 15 mm after 30 minutes at 250degreesC in the heat sag test. Independent claims are also included for (1) (1) a polymer composition comprising (A) a polyamide, (B) a syndiotactic monovinylaromatic homo- or co-polymer, (C) a polystyrene copolymer or graft copolymer and (D) an impact modifier (2) (2) car body panelling parts made from (I), comprising mud guards, bumpers, side parts, tank flaps, doorsill strips and/or door shells (3) (3) the production of such parts by injection moulding and/or gas pressure processes .
