Title:

POLYCARBONATE RESIN COMPOSITION AND HOT RADIATION SHIELDING MOLDED PRODUCT

Document Type and Number:

WIPO Patent Application WO/2006/103906

Kind Code:

A1

Abstract:

This invention provides a polycarbonate resin composition comprising 100 parts by weight of an aromatic polycarbonate resin having a terminal hydroxyl group concentration in the range of 100 to 1800 ppm and 0.0001 to 5 parts by weight of fine particles of boride of at least one metal selected from the group consisting of La, Ce, Pr, Nd, Tb, Dy, Ho, Y, Sm, Eu, Er, Tm, Yb, Lu, Sr and Ca. A hot radiation shielding molded product produced by molding the polycarbonate resin composition is also provided. In particular, the polycarbonate resin composition and hot radiation shielding molded product have low haze, excellent transparency, low solar radiation transmittance, satisfactory hot radiation shielding properties (particularly the function of permitting the transmission of visible light and selectively shielding infrared light), and excellent mechanical strength and heat stability on melting and thus are suitable for use, for example, in window glass for general buildings or vehicles, roof materials for arcades, carports and the like, optical materials such as infrared cut filters, and agricultural films.
