PURPOSE:To obtain a styrene resin composition which can give a molding which is excellent in slidability and free of burn marks and does not suffer any decrease in mechanical and thermal properties, by mixing a styrene resin composition with a silicone oil and a tin stabilizer in a specified mixing ratio. CONSTITUTION:This resin composition comprises a styrene resin, a silicone oil and a tin stabilizer, and the content of said silicone oil is 0.3-5.0wt.% based on the composition and that of said tin stabilizer is 0.05-3.0wt.% based on the composition. When the content of said silicone is below 0.3wt.% based on the composition, the effect of said tin stabilizer added is not marked. When it is above 5.0wt.%, the properties of the obtained composition are markedly deteriorated. When the content of said tin stabilizer is below 0.05wt.% based on the composition, the effect of its addition is small. When it is above 3.0pts. wt., the properties of the obtained composition are markedly deteriorated. |
