The present invention relates to a transparent polymethyl methacrylate / polycarbonate resin composition,n n n More specifically, polymethyl methacrylate resin and polycarbonate resin having an appropriate range of molecular weight are selected or polymethyl methacrylate / poly is adjusted to an appropriate level of molecular weight by using an additive capable of adjusting the molecular weight of polycarbonate. The carbonate blend has the advantage of providing a transparent polymethyl methacrylate / polycarbonate blend through the extrusion process without any polymerization process, regardless of the type of PC (does not have a hydroxyl group at the end of the chain). |
