LOW GLOSS THERMOPLASTIC RESIN COMPOSITION USING MICROPARTICLE

摘要

PURPOSE: A thermoplastic resin composition using microparticle is provided, to lower the gloss with suppressing the deterioration of the mechanical properties. CONSTITUTION: The thermoplastic resin composition comprises 10-50 parts by weight of the graft copolymer resin prepared by copolymerizing 10-30 parts by weight of a cyano vinyl compound and 70-90 parts by weight of an aromatic vinyl compound to 30-60 parts by weight of a rubbery polymer; 40-80 parts by weight of the copolymer consisting of 20-40 wt% of a cyano vinyl compound and 60-80 wt% of an aromatic vinyl compound; and 1-50 parts by weight of a crosslinkable organic microparticle. Preferably the crosslinkable organic microparticle is prepared by dispersing a polymer organic dispersant aqueous solution and a solution containing a crosslinkable monomer, an initiator and a polymerizable monomer to a drop of 0.1-3.0 micrometers and polymerizing it at a temperature of 50-80 deg.C, and has a particle size of 1-20 micrometers.
