| titleOfInvention | Methacrylic resin composition and injection-molded article |
| abstract | A methacrylic resin composition comprising not less than 90% by mass of a methacrylic resin, wherein the methacrylic resin comprises 95 to 100% by mass of methyl methacrylate monomer units and 0 to 5% by mass of acrylate monomer units, the methacrylic resin has an Mw of 57000 to 90000, Mw representing a weight-average molecular weight, and a ratio Mw/Mn of not more than 1.9, Mn representing a number-average molecular weight, the methacrylic resin composition has an absolute value of a difference between YI4 and YI2 of not more than 3, YI4 representing a yellow index at an optical path length of 200 mm of an injection-molded article obtained at a cylinder temperature of 280° C. in a molding cycle of 4 minutes, YI2 representing a yellow index at an optical path length of 200 mm of an injection-molded article obtained at a cylinder temperature of 280° C. in a molding cycle of 2 minutes, and meets a relationship represented by Formula (B) and Formula (C): n R≥11 Formula (B)n n 0.8<R/E<1.2 Formula (C)n n where R represents the melt flow rate of the methacrylic resin composition as measured at 230° C. under a load of 3.8 kg, the melt flow rate R being expressed in g/10 min; and E represents a value calculated by Formula (A), the value E being expressed in g/10 min, the Formula (A) being E=exp (0.17112×W−0.00399×P+5.09713) where W represents the ratio of acrylate monomer units to the total monomer units in the methacrylic resin, the ratio W being expressed in % by mass; and P represents the degree of polymerization of the methacrylic resin. |
