  • Patent number: 6908953
    Abstract: The present invention is directed to polymerizable dental compositions containing (a) 3 to 80 wt. % of cycloaliphatic epoxides; b) 0 to 80 wt. % of an epoxide or a mixture of epoxides which are different from a); c) 3 to 85 wt. % of a filler material; d) 0.01 to 25 wt. % of initiators, inhibitors and/or accelerators; e) 0 to 25 wt. % of auxiliary agents, the individual percentages of which are in relation to the total weight. The new polymerizable agents are particularly suited as dental material.

  • Patent number: 6852775
    Abstract: The invention relates to polymerizable dental compositions which contain (a) 10 to 98.999 wt.-% of at least one bi- or higher-functional ethylenically unsaturated monomer, (b) 0 to 88.999 wt.-% of at least one monofunctional ethylenically unsaturated monomer, (c) 0 to 5 wt.-% of an accelerator, (d) 0.001 to 5 wt.-% of a redox initiator system which can trigger the radical polymerisation and (e) 0 to 88.999 wt.-% fillers, thixotropic auxiliaries, retarders and other auxiliaries (f) 1 to 30 wt.-% of a customary plasticizer and are characterized in that the redox initiator system comprises (i) a barbituric acid derivative and/or a malonyl sulfamide and (ii) an organic peroxide, selected from the group of the mono- or multifunctional carboxylic acid peroxyesters, and the constituents (a) to (f) are present in two pastes spatially separated from each other.

  • Patent number: 6852822
    Abstract: The invention provides processes for making low viscosity condensates, condensates per se, and processes for making polymers from these condensates. The invention also encompasses the polymer products of these processes, especially articles for dental use. The condensates per se of the invention are of hydrolyzable silanes. The condensates can contain one or more elements selected from the group consisting of B, AI, P, Sn, Pb, the transition metals, the lanthanides and the actinides. Processes of the invention for making polymers from the condensates optionally include use of compounds that can be polymerized ionically or by radical reactions in addition to the hydrolyzable silanes. Curing of the polymers is optionally performed by photochemical, thermal or by redox-induction methods.

  • Patent number: 6624236
    Abstract: The invention relates to polysiloxanes from cross-linkable monomers based on cyclosiloxanes and their use in polymerizable compositions. The invention relates in particular to polysiloxanes from sol-gel-condensable cyclosiloxane(meth)acrylates as well as resinous compositions, obtainable by hydrolytic condensation of one or more hydrolyzable and condensable cyclosiloxane(meth)acrylates.
