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.-

摘要: Radically polymerizable dental material, which comprises a catalyst paste and a base paste, wherein the catalyst pastes comprises an oxidizing agent, preferably a peroxide or hydroperoxide, a radically polymerizable monomer and/or oligomer with acid group and a polyfunctional radically polymerizable monomer, and the base paste comprises a polyfunctional radically polymerizable monomer without an acid group and a dihydropyridine derivative of Formula (I)
wherein R1 is a C6-C10 aryl group, preferably a phenyl group, which can be unsubstituted or substituted; R2-6 independently of each other are a hydrogen atom, a C1-C20 alkyl group that can be interrupted by one or more of an S atom, O atom, -C(O)O- group and/or -C(O)NH-group, and/or can be unsubstituted or substituted; a C3-C16 cycloaliphatic group that can be unsubstituted or substituted; or a C7-C20-alkylaryl group that can be interrupted by one or more of an S atom, O atom, -C(O)O- group and/or -C(O)NH- group and/or can be unsubstituted or substituted; n is 1, 2, 3 or 4. The material comprises at least 50 % by weight of polyfunctional radically polymerizable monomers or monomers and oligomers, based on the total amount of radically polymerizable monomers and oligomers. The material has good mechanical properties and does not exhibit a bitter taste.-

摘要: The present invention provides a paste-form two-pack type dental curable composition having an adequate working time range and superior bond strength to dentin, in addition to showing small variation in working time, small decline in bond strength to dentin, and low risk of paste solidification over extended storage. The present invention relates to a paste-form two-pack type dental curable composition comprising: a first agent that comprises an acidic group-containing polymerizable monomer (A), an acidic group-free polymerizable monomer (B), an organic peroxide (C), a nitrogen atom-containing ligand (D), and a filler (E); and a second agent that comprises an acidic group-free polymerizable monomer (B), a thiourea compound (F), and a filler (E).

摘要: Radikalisch polymerisierbare Zusammensetzung, die mindestens ein polyfunktionelles radikalisch polymerisierbares Monomer ohne Säuregruppe, mindestens ein säuregruppenhaltiges radikalisch polymerisierbares Monomer und/oder mindestens ein saures Oligomer, mindestens einen Fluoroaluminiumsilikatglasfüllstoff und/oder röntgenopaken Glasfüllstoff und mindestens einen Initiator für die radikalische Polymerisation enthält, wobei der Fluoroaluminiumsilikatglasfüllstoff und/oder röntgenopake Glasfüllstoff mit einem Kieselsäure(hetero)polykondensat beschichtet ist. Die Zusammensetzung zeichnet sich durch eine hohe Stabilität aus und eignet sich besonders als Dentalwerkstoff.
