摘要:
The invention concerns a dental composition comprising bisacrylamides that are polymerizable by free-radical polymerization and by Michael-addition polymerization with amines. 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.
