preparation example Construction

[0116] In the preparation of the polycarbonate-polysiloxane copolymer, the amount of dihydroxypolydiorganosiloxane is selected so as to provide the desired amount of polydiorganosiloxane units in the copolymer. The amount of polydiorganosiloxane units can vary widely, for example it can be from about 1 wt% to about 99 wt% polydimethylsiloxane, or an equimolar amount of additional polydiorganosiloxane, with the remainder carbonate unit. Therefore, the specific amount is determined according to the desired physical properties of the thermoplastic composition, the D value (in the range of 2 to about 1000) and the type and relative amount of each component in the thermoplastic composition, the type and relative amount of each component The amount includes the type and amount of polycarbonate, the type and amount of impact modifier, the type and amount of polycarbonate-polysiloxane copolymer, and the type and amount of any other additives. The appropriate amount of dihydroxypolydi...

Abstract

A thermoplastic composition comprising in combination a polycarbonate component; a functionalized silane coupling agent; an impact modifier; and a filler is disclosed. The composition optionally comprises a polycarbonate-polysiloxane copolymer and / or a flame retardant. The compositions have a good balance of properties, and if desired, are also flame retardant.

Description

Background technique [0001] The present invention relates to thermoplastic compositions comprising aromatic polycarbonates, methods of their manufacture and methods of their use, and in particular filled thermoplastic polycarbonate compositions having improved mechanical properties. [0002] Aromatic polycarbonates are used to make articles and components for a wide variety of applications, from automotive components to electronics. Impact modifiers are often added to aromatic polycarbonates to increase the toughness of the composition. Impact modifiers tend to have a relatively rigid thermoplastic phase and an elastomeric (rubber) phase, and can be formed by bulk or emulsion polymerization. Polycarbonate compositions comprising acrylonitrile-butadiene-styrene (ABS) impact modifiers are generally described, for example, in US Patent No. 3,130,177. Polycarbonate compositions comprising emulsion polymerized ABS impact modifiers are described inter alia in US Publication 2003 / 0...
