A resin composition includes a phosphorus-based acrylic copolymer (A) including (a1) an acrylic monomer represented by Formula 1 and (a2) a phosphorus-based acrylic monomer represented by Formula 2 as defined in the specification. The resin composition can have flame retardancy, heat resistance, mechanical properties, and/or flowability, while maintaining properties of high transparency and scratch resistance.

Transparent thermoplastic resin composition

The present invention relates to an environmentally friendly flame-retardant polycarbonate resin composition having scratch resistance, which includes a specific (meth)acrylic flame-retardant copolymer to improve flame retardancy and scratch resistance.

Flame-retardant polycarbonate resin composition with scratch resistance

The present invention provides a flame-retardant and scratch-resistant polycarbonate resin composition including a (meth)acrylic flame-retardant copolymer.

Flame-retardant and scratch-resistant polycarbonate resin composition

A polycarbonate resin composition can have improved transparency and scratch resistance of the present invention and comprises about 10 to about 99% by weight of polycarbonate resin (A); and about 1 to about 90% by weight of acrylic copolymer with ultra-low molecular weight and high refractive index (B). The resin composition of the present invention can further comprise acrylic resin (C). The acrylic copolymer with ultra-low molecular weight and high refractive index (B) can have a refractive index of about 1.495 to about 1.590 and a weight average molecular weight of about 3,000 to about 40,000 g/mol.

Polycarbonate resin composition with improved transparency and scratch-resistance

An eco-friendly (meth)acrylic flame retardant copolymer includes a phosphorous-based acrylic monomer to provide a high index of refraction and excellent flame retardancy.

(Meth)acrylic-based flame retardant copolymer and method for manufacturing the same

An aromatic vinyl thermoplastic resin composition includes (A) about 10 to about 99% by weight of a thermoplastic resin (A) including (a1) an aromatic vinyl copolymer resin, (a2) a rubber-modified vinyl graft copolymer, or a combination of (a1) and (a2); and (B) about 1 to about 90% by weight of a branched aromatic vinyl copolymer resin including a silicon based compound. The branched aromatic vinyl copolymer includes a copolymer prepared by copolymerizing (b1) about 10 to about 85% by weight of an aromatic vinyl based monomer; (b2) about 10 to about 85% by weight of an unsaturated nitrile based monomer; (b3) about 1 to about 50% by weight of an aromatic methacrylate, aliphatic methacrylate, or a combination thereof; and (b4) about 0.1 to about 20% by weight of a silicon based compound having two or more unsaturated functional groups.
