The present invention provides at least one thermoplastic having a glass transition temperature of at least about 220 ° C., having an average particle size in the range of about 100 nanometers, and a refractive index in the range of about 1.4 to about 3. The present invention relates to a polymer composition comprising inorganic particles dispersed in the above thermoplastic resin having at least one of an effective amount for dispersing inorganic particles in the thermoplastic resin. The polymer composition is a high-temperature thermoplastic material suitable for forming an optical article (for example, a lens) by, for example, molding using a mold. |
