<P>PROBLEM TO BE SOLVED: To provide a resin-molded article for an optical use superior in heat resistance and moisture absorption and controlled warp and deformation of the article at high temperature and high humidity. <P>SOLUTION: The molding method of the resin-molded article is characterized in that 1 to 90 wt.% of a (co)polymer (A) comprising 0 to 10 wt.% of an alkyl(meth)acrylate-based monomer and 100 to 90 wt.% of an aromatic vinyl-based monomer, and 99 to 10 wt.% of a polycarbonate resin (B), each in a pellet form, are directly fed into an injection molding machine, and that a melt volume flow rate (MVR, measured at 220°C under 10 kg according to ISO 1133) of the (co)polymer (A) is 1 to 50 times as large as MVR of the polycarbonate resin (B). <P>COPYRIGHT: (C)2008,JPO&INPIT |
