Abstract
Disclosed herein is a thermoplastic resin composition having excellent scratch resistance and a method for preparing the same. The thermoplastic resin composition comprises (A) about 80 to about 95% by weight of a terpolymer of (meth)acrylic acid alkyl ester-aromatic vinyl-cyanide vinyl compound; and (B) about 5 to about 20% by weight of a butadiene rubber.
Claims17
A thermoplastic resin composition having excellent low gloss characteristic and scratch resistance, the composition comprising:
- (A) about 80 to about 95% by weight of a continuous phase formed of a terpolymer of (meth)acrylic acid alkyl ester-aromatic vinyl-cyanide vinyl compound;
- and
- (B) about 5 to about 20% by weight of rubber particles as a dispersed phase, wherein said rubber particles are butadiene rubber particles with 0 wt % styrene monomer and wherein said rubber particles have an average particle diameter of about 3 to about 10 μm,
- wherein said terpolymer of (meth)acrylic acid alkyl ester-aromatic vinyl-cyanide vinyl compound (A) is a terpolymer 85 to 90% by weight of (meth)acrylic acid alkyl ester, about 5 to 12% by weight of an aromatic vinyl compound, and about 1 to about 10% by weight of a cyanide vinyl compound.
A method for preparing a thermoplastic resin composition having excellent low gloss characteristic and scratch resistance, the method comprising:
- preparing a reaction solution by mixing a monomer mixture comprising about 70 to about 90% by weight of (meth)acrylic acid alkyl ester, about 5 to about 20% by weight of an aromatic vinyl compound, and about 1 to about 10% by weight of a cyanide vinyl compound with butadiene rubber particles with 0 wt % styrene monomer having an average particle diameter of about 3 to about 10 μm;
- and
- polymerizing the reaction solution by continuously introducing the reaction solution into a plurality of serially connected reactors to a final monomer conversion of about 50 to about 70%.
