POLYCARBONATE RESIN COMPOSITION AND HOT RADIATION SHIELDING MOLDED PRODUCT
The present invention relates to a polycarbonate resin composition comprising 100 parts by weight of aromatic polycarbonate resin having a concentration of end hydroxyl group of 100 to 1800 ppm and 0.0001 to 5 parts by weight of fine particle of boride of at least one metal selected from the group consisting of La, Ce, Pr, Nd, Tb, Dy, Ho, Y, Sm, Eu, Re, Tm, Yb, Lu, Sr and Ca, and a heat ray shielding molded product formed by molding the above polycarbonate resin composition. The polycarbonate resin composition and heat ray shielding molded product composed thereof according to the present invention, have especially low haze, are excellent in transparency, have low solar transmittance and sufficient heat ray shielding property (especially, have a function of transparency for visible light and selectively shielding property for infrared ray), and are excellent in mechanical strength and thermal stability at melting. Therefore, these are suitably applicable for windows of general buildings or vehicles, roof materials of arcades and carports, optical materials such as infrared ray cut filters, films for agriculture or the like.
