Abstract: A thermoplastic resin composition comprising a graft copolymer (I) which is produced by carrying out the graft polymerization of a monomer mixture (B) comprising an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of an acrylic rubbery polymer (A) and a vinyl copolymer (II) which is produced by carrying out the copolymerization of an aromatic vinyl monomer with a vinyl cyanide monomer, wherein the ratio of the content of the for mer copo lymer to that of the latter copolymer is (30 to 70 parts by weight):(70 to 30 parts by weight), the graft copolymer(I) has such a property that the ratio (i.e., (a)/(?)) of the gel swelling degree (a) of the acrylic rubbery polymer (A) in toluene to the grafting ratio (? ) of the graft copolymer (I) is 0.4 to 2.0, and the thermoplastic resin composition has such a structure that particles of the graft copolymer (I) are aggregated in the thermoplastic resin composition. From the thermoplastic resin composition, a molded article having excellent fluidability, weather resistance and impact resistance can be produced.

Abstract: Una composición de resma termoplástica que comprende un copolímero de injerto (I) que se produce al llevar a cabo la polimerización de injerto de una mezcla de monómeros (B) que comprende un monómero de vinilo aromático y un monómero de cianuro de vinilo en presencia de un polímero gomoso acrílico (A) y un copolímero de vinilo (II) que se produce al llevar a cabo la copolimerización de un monómero de vinilo aromático con un monómero de cianuro de vinilo, en donde la relación del contenido del primer copolímero a la del último copolímero es (30 a 70 partes en peso):(70 a 30 partes en peso), el copolímero de injerto (I) tiene una propiedad tal que la relación (es decir, (a)/(ß)) del grado de hinchamiento en gel (a) del polímero gomoso acrílico (A) en tolueno a la relación de injerto (ß) del copolímero de injerto (I) es 0.4 a 2.0, y la composición de resma termoplástica tiene una estructura tal que las partículas del copolímero de injerto (I) se agregan en la composición de resina termoplástica. A partir de la composición de resina termoplástica, se puede producir un artículo moldeado que tenga una excelente fluidez, resistencia a la intemperie y resistencia a impactos.
