Abstract

An inorganic glass having an aliphatic polymer covalently bonded to the surface thereof is disclosed for providing improved adhesion to a matrix polymer when the glass is employed as a composite filler, as well as for the formation of a composite absent a separate matrix polymer. The polymer is grafted onto the glass by a method which includes the steps of pretreating the surface of the glass with an activator which an activating moiety to the surface, functionalizing the pretreated surface by bonding functional moieties thereto, and polymerizing a cycloaliphatic monomer onto the functionalized surface in the presence of a ring opening polymerization catalyst. Also disclosed are novel inorganic glasses which contain both silicate and phosphate linkages.
