THERMOPLSTIC RESIN COMPOSITION WITH GOOD LOW GLOSS WEATHER RESISTANT PROPERTY AND MECHANICAL PROPERTIES AND EXTRUDED ARTICLES PRODUCED FROM THE SAME

摘要

The present invention relates to a thermoplastic resin composition which is excellent in low light properties, weather resistance and mechanical properties and an extruded article produced therefrom, comprising 40 to 70% by weight of an aromatic vinyl compound-vinyl cyanide copolymer as a matrix resin; (a) an acryl-based graft copolymer which is obtained by grafting from 46 to 95% by weight of an aromatic vinyl compound-vinyl cyanide copolymer to 5 to 54% by weight of a (meth) acrylate rubbery polymer having an average particle diameter of 0.05 to 1 탆, 40% by weight; (b) 5 to 45% by weight of an aromatic vinyl compound-vinyl cyanide copolymer and 1 to 10% by weight of an acrylic graft copolymer grafted on 55 to 95% by weight of a (meth) acrylate rubbery polymer having an average particle size of 0.05 to 1 m weight%; And (c) 1 to 20 wt% of a large-diameter diene-based graft copolymer grafted on 5 to 20 wt% of a diene-based rubbery polymer having 80 to 95 wt% of an aromatic vinyl compound-vinyl cyanide copolymer and having an average particle size of 1 to 20 μm %; And a thermoplastic resin composition excellent in low light properties, weather resistance and mechanical properties, and an extruded article produced therefrom.
