われ開示されている。BACKGROUND OF THE INVENTION Generally, compositions of polycarbonate and polymethyl methacrylate do not form a uniform transparent resin as described in Japanese Patent Publication No. 16063/1982, but instead form an opaque resin with pearlescent luster. Therefore, compositions that maintain the high transparency possessed by both resins have been studied and disclosed.

。Japanese Patent Publication No. 56-28937 describes a composition of a low molecular weight acrylic copolymer consisting of polycarbonate and 75 to 90% by weight of methyl methacrylate and 10 to 25% by weight of alkyl acrylate. However, in order for the acrylic copolymer to become transparent when mixed with polycarbonate, it is necessary to reduce the molecular weight to 15,000 or less, and such low-molecular-weight substances only act as plasticizers, and when mixed in large quantities, they can cause significant damage. This causes a decrease in physical properties.

Compositions of polycarbonate and copolymers of ~C10 alkyl (meth)acrylates and ultraviolet absorbing monomers are described. The copolymers are very specialized and expensive, making them impossible to use on a wide scale. JP-A-63-90551 discloses a copolymer of methyl methacrylate and monosubstituted (meth)acrylamide, and JP-A-63-256647 discloses a copolymer of methyl methacrylate and maleimide. 1986-1
No. 749 describes that a copolymer consisting of methyl methacrylate and a (meth)acrylate having a carbocyclic group is transparently compatible with polycarbonate, but in both cases, the copolymer is transparently compatible with polycarbonate at the temperature at which polycarbonate is normally melt-molded. There are 2
At 50 to 300°C, a thin film appears transparent, but when the thickness is several mm, it becomes opaque, which poses a practical problem.
