Patent ID: 6919408

Claim:
A thermoplastic transparent resin composition comprising: 3-15 parts by weight of small aperture polybutadiene rubber latex; 5-25 parts by weight of large aperture polybutadiene rubber latex; 40-70 parts by weight of a methacrylic acid alkylester compound or an acrylic acid alkylester compound; 15-30 parts by weight of an aromatic vinyl compound; and 1-20 parts by weight of a vinylcian compound, wherein the small aperture polybutadiene rubber latex has a particle diameter of 600-1500 Å, a gel content of 70-95%, and a swelling index of 12-30, and the large aperture polybutadiene rubber latex has a particle diameter of 2600-5000 Å, a gel content of greater than 80 and not exceeding 95%, and a swelling index of 12-30, wherein the large aperture polybutadiene rubber latex with a gel content of greater than 80 and not exceeding 95% is produced by adhering small aperture polybutadiene rubber latex particles with a gel content of 70-95%, wherein a total refraction coefficient of the composition, excluding the polybutadiene rubber latex, is between 1.510 and 1.526.
