POLYMER MATERIAL CONTAINING DISPERSED LAYERED SILICA AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a polymer material containing dispersed layered silica, having high transparency, high heat resistance and high hardness by a new dispersed state different from that in which conventional silica particles of nanometer order are dispersed in a polymer accompanied by flocculation. SOLUTION: The polymer material containing dispersed layered silica is obtained by mixing and dispersing colloidal silica of nanosize into a solvent containing a dissolved polymer such as polymethyl methacrylate, polystyrene, etc., then separating the silica-containing polymer and then heat pressing the silica-containing polymer.
