ACRYLONITRILE-BUTADIENE-STYRENE RESIN COMPOSITION HAVING EXCELLENT CHEMICAL-RESISTANCE

摘要

PURPOSE: An acrylonitrile-butadiene-styrene resin composition is provided which shows reinforced chemical-resistance to engine related chemicals such as a brake oil having a strong solventability and is thus useful for coating a car. CONSTITUTION: The acrylonitrile-butadiene-styrene resin composition comprises: (i) 10-50 part by weight of a grafted acrylonitrile-butadiene-styrene resin consisting of 40-60 part by weight of a gummy polymer having an average particle size of 0.20-0.50 micrometer and 40-60 part by weight of a gummy polymer having an average particle size of 0.08-0.20 micrometer; (ii) 50-90 part by weight of a styrene-acrylonitrile resin consisting of 65-78 part by weight of a styrene and 22-35 part by weight of an acrylonitrile; and (iii) 0.1-3.0 part by weight of a polyethylene wax copolymer.
