PROBLEM TO BE SOLVED: To provide a glass fiber-reinforced methacrylic resin composition having excellent impact resistance and heat resistance, and low birefringence.SOLUTION: The glass fiber-reinforced methacrylic resin composition includes 100 pts.wt. of a methacrylic copolymer (A) comprising (i) a repeating unit derived from a methacrylate monomer, (ii) a repeating unit derived from a vinyl aromatic monomer, and (iii) a repeating unit of acid anhydride, wherein the molar ratio of (iii) to (ii) is more than 1 and not more than 10, and the total amount of the residual monomers is ≤0.5 pts.wt. based on 100 pts.wt. of the copolymer; and 5-100 pts.wt. of a glass fiber (B). |
