Filled polymer blends comprising a polycarbonate, a rubber modified copolymer of a vinyl aromatic monomer and from 4 to 18 weight percent of an inorganic filler.

Filled polymeric blend

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.

Filled carbonate polymer blend compositions

The invention relates to a method for the coextrusion of a plate-shaped product In the method according to the invention at least one coating layer is provided by means of coextrusion which is composed of a special polymer mixture This mixture enables obtaining a matt surface and can be provided very uniformly on the major layer of polycarbonate by coextrusion The polymer mixture comprises 84-92% by weight of polycarbonate, 4-8% by weight of talcum and 4-8% by weight of a mattifying agent based on acrylate copolymers
