THERMOPLASTIC RESIN COMPOSITION HAVING EXCELLENT JET- BLACK COLOR

摘要

PURPOSE:To provide a thermoplastic resin compsn. having an excellent jet-black color, by blending two specified carbon blacks having different properties with an AES resin. CONSTITUTION:100-5wt% graft polymer (A) obtd. by graft-polymerizing an arom. vinyl compd. (e.g. styrene or vinyltoluene), a vinyl cyanide compd. (e.g. acrylonitrile), etc. onto an ethylene/propylene rubbery copolymer is mixed with 0-95wt% arom. vinyl/vinyl cyanide copolymer to prepare an AES resin. 0.2- 3pts.wt. carbon black having a specific surface area of 400m<2>/g or above and a DBP oil absorption of 80ml/100g or above and 0.2-5pts.wt. carbon black having a specific surface area of 100-4002/g and a DBP oil absorption of 50ml/100g or above are mixed with 100pts.wt. AES resin to obtain the desired thermoplastic resin compsn.
