ALUMINA ULTRAFINE PARTICLE-DISPERSED SOLUTION AND ALUMINA ULTRAFINE PARTICLE-DISPERSED MOLDING

摘要

PROBLEM TO BE SOLVED: To provide an alumina ultrafine particle-dispersed solution which is excellent in dispersibility and dispersion stability and which is hardened to obtain a molding excellent in optical properties of transparency, hue or the like, mechanical properties and various physical properties of flame retardance or the like.;SOLUTION: The alumina ultrafine particle-dispersed solution contains a polymerizable monomer as component (A), alumina ultrafine particles as component (B), a surface finishing agent as component (C) and the compound shown by formula (1) (wherein R is an 8-24C alkyl group; and n is an integer satisfying 2≤n≤16) as component (D) at the least. The alumina ultrafine particle-dispersed molding is obtained by heating/hardening the alumina ultrafine particle-dispersed solution.;COPYRIGHT: (C)2009,JPO&INPIT
