| 摘要 |
The present invention relates to a polymer resin composition comprising: a polyester resin including a residue of dicarboxylic acid component containing a terephthalic acid, five to 60 mole percent of isosorbide, 10 to 80 mole percent of cyclohexanedimethanol, and a residue of diol component containing a remaining amount of other diol components; a polycarbonate resin; an impact reinforcement including, based on 100 parts by weight of the whole impact reinforcement, 40-90 parts by weight of a core of a butadiene copolymer, 5-40 parts by weight of an inner layer shell formed by polymerizing a monomer mixture containing (meth)acrylic acid ester monomer having a hydroxyl group or an alkoxy group, and 5- 20 parts by weight of an outer shell formed by polymerizing a monomer mixture containing an aromatic vinyl monomer. The present invention provides an eco-friendly polymer resin composition having improved mechanical properties of high heat resistance, impact resistance, etc. |
