Title:
MOLDED POLYCARBONATE MATERIALS HAVING IMPROVED MELT FLOW BEHAVIOR AND RESISTANCE TO CHEMICALS
Document Type and Number:
WIPO Patent Application WO2005000962
Kind Code:
A3
Abstract:
The invention relates to rubber-modified polycarbonate compositions containing vinyl resin, especially acrylonitirile-butadiene-styrol copolymer (ABS), and low-molecular vinyl (co)polymers which comprise an a-methylstyrol moiety of less than 22 percent by weight and/or an acrylate moiety of more than 0 and less than 22 percent by weight relative to the copolymer C) at an average molecular weight Mw of 1500 to 5000 g/mole and a glass transition temperature Tg of > 40 DEG C. The inventive polycarbonate compositions are characterized by an improved melt flow behavior and better resistance to chemicals.
