摘要： The present application provides a polyamide resin composition and a molded article comprising the same. The polyamide resin composition includes: 100 parts by weight of a polyamide resin including 5% by weight (wt%) to 55 wt% of an aromatic polyamide resin and 45 wt% to 95 wt% of an aliphatic polyamide resin; 100 parts by weight to 200 parts by weight of glass fiber; 20 parts by weight to 25 parts by weight of a poly(ether ester amide) block copolymer; and 0.1 parts by weight to 2 parts by weight of talc, wherein the poly(ether ester amide) block copolymer is a block copolymer of a reaction mixture including an amino carboxylic acid having 6 or more carbon atoms, a lactam or a salt of diamine-dicarboxylic acid, polytetramethylene glycol, and a dicarboxylic acid having 4 to 20 carbon atoms. The polyamide resin composition has good properties in terms of bonding strength and detachability with respect to a polyurethane bonding agent, impact resistance, heat resistance, rigidity, and the like.

摘要： A thermoplastic resin composition according to the present invention comprises: about 100 parts by weight of a polycarbonate resin; about 5 to about 15 parts by weight of a first rubber-modified vinyl-based graft copolymer in which a monomer mixture is graft-polymerized to a rubber polymer, the monomer mixture containing an aromatic vinyl-based monomer and a cyanovinyl-based monomer; about 2 to about 8 parts by weight of a second rubber-modified vinyl-based graft copolymer in which an alkyl (meth)acrylate-based monomer is graft-polymerized to a rubber polymer; about 0.5 to about 2 parts by weight of a siloxane copolyester; about 17 to about 40 parts by weight of talc; and about 13 to about 23 parts by weight of a phosphorus-based flame retardant, wherein the weight ratio of the first rubber-modified vinyl-based graft copolymer to the second rubber-modified vinyl-based graft copolymer is about 1 : 0.15 to about 1 : 0.8, and the weight ratio of the combined weight of the first rubber-modified vinyl-based graft copolymer and the second rubber-modified vinyl-based graft copolymer to the siloxane copolyester is about 1 : 0.03 to about 1 : 0.1. The thermoplastic resin composition is excellent in terms of impact resistance, hardness, mar resistance, flame retardancy, physical property balance thereof, and the like.
