Abstract

The invention relates to a polymeric composition, comprising: at least one thermoplastic resin having a glass transition temperature of at least about 220° C.; inorganic particulates having an average particle size in the range up to about 100 nanometers dispersed in the thermoplastic resin, the inorganic particulates having an index of refraction in the range from about 1.4 to about 3; and an effective amount of at least one dispersant to disperse the inorganic particulates in the thermoplastic resin. The polymer composition may be a high temperature thermoplastic suitable for forming, such as by molding, optical articles such as lenses.
