Abstract: A process for the preparation of composite filler particles, comprising: (a) coating a particulate filler having a median particle size (D50) of from 1 to 1200 nm; (b) agglomerating the coated particulate filler, for providing a granulation of the coated particulate filler wherein the granulation contains the coated particulate filler particles whereby the at least one coating layer may be crosslinked by crosslinking groups obtained by reacting the reactive groups and optionally a further crosslinking agent.

Abstract: The invention concerns a dental composition comprising bisacrylamides that are polymerizable by free-radical polymerization and by Michael-addition polymerization with amities. The application of polymerization and addition polymerization with amines opens the possibility to completely reacted materials that have no oxygen inhibited layers. The claimed bisacrylamides have an improved hydrolytic stability.
