A thermoplastic resin composition comprising (A) 5 to 75 % by weight of a glutarimide copolymer which comprises 5 to 99.5 % by mol of repeating units derived from glutarimide, 0.5 to 10 % by mol of repeating units derived from an acid and/or acid anhydride and 0 to 94.5 % by mol of repeating units derived from an .alpha.,.beta.-ethylenically unsaturated monomer, (B) 10 to 80 % by weight of a saturated polyester, (C) 10 to 80 % by weight of a rubber-containing copolymer obtainable by polymerizing, in the presence of (1) 10 to 80 % by weight of a rubbery polymer, (2) 20 to 90 % by weight of at least one .alpha.,.beta.-ethylenically unsaturated monomer selected from the group consisting of an aromatic .alpha.,.beta.ethylenically unsaturated monomer, a cyano group-containing .alpha.,.beta.-ethylenically unsaturated monomer and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid ester monomer, and (D) 0.1 to 20 % by weight of an epoxy group-containing copolymer, which composition has an excellent combination of good heat resistance, good impact resistance, high stiffness, good oil resistance and good solvent resistance.
