Abstract
Vitreous filler material for incorporation into a polymerizable matrix, including a filler material which is vitreous; a polymerization catalyst; and a fixing agent which is applied to at least a part of the surface of the filler material and which affixes the polymerization catalyst to the surface of the filler material. Fixing catalyst to the surface of the filler material prior to its being contacted with the polymerizable matrix material facilitates good distribution of the catalyst within the polymerizable matrix material, and advantageously allows rapid catalytic action and a reduction in the amount of catalyst required.
