摘要： Acylthiourea oligomers according to the formula
The acylthiourea oligomers, in combination with a hydroperoxide compound, are active as initiators for the radical polymerization. Radically polymerizable compositions comprising at least one acylthiourea, at least one hydroperoxide and at least one radically polymerizable monomer are particularly suitable as dental materials.-
