ABSTRACT:
Blends of (a) a carbonate polymer component and (b) a monovinylidene aromatic copolymer component not containing a grafted rubber polymer component and (c) an inorganic filler component are prepared having improved combinations of processability, resistance to linear thermal expansion and low temperature toughness. Specifically shaped, small particle size fillers (c) are preferably employed which provide the resistance to linear thermal expansion and maintain the impact resistance of the filled blend.
