The invention relates to polymerizable materials comprising two components, where component I comprises: (a) from 0.1 to 20% by weight of at least one vinyl ether, (b) from 10 to 89.9% by weight of at least one ethylenically unsaturated monomer which is not a vinyl ether, (c) from 0.001 to 5% by weight of at least one accelerator, (d) from 9.999 to 89.899% by weight of fillers, thixotropy assistants, retardants and other auxiliaries, and component II comprises: (e) from 0.1 to 20% by weight of at least one barbituric acid derivative and/or at least one malonylsulfamide which is able to initiate the free-radical polymerization, and (f) from 0 to 89.9% by weight of fillers, thixotropy assistants, retardants and other auxiliaries, (g) from 10 to 80% by weight of conventional plasticizers, and to the use thereof.
A polymerizable material comprising two components, where
A polymerizable material as claimed in the preceding claim, where component (a) is selected from the group consisting of:
A polymerizable material as claimed in the preceding claim, where component (a) is selected from the group consisting of:
A polymerizable material as claimed in one of the preceding claims, where component (a) is liquid at room temperature.
A polymerizable material as claimed in one of the preceding claims, where component (a) also carries additional functional groups.
A polymerizable material as claimed in one of the preceding claims, where component (a) is at least difunctional.
The use of a polymerizable material as claimed in one of the preceding claims in the dental sector.
The use of vinyl ethers in materials which can be polymerized by means of initiator systems based on at least one barbituric acid derivative and/or malonylsulfonamide which is able to initiate free-radical polymerization, for increasing the mechanical values at the same time as lowering the maximum setting temperature.
