The invention relates to a composition which is polymerizable by ring-opening metathesis polymerization (ROMP) comprising at least one monomer that is polymerizable by ROMP, at least one initiator of the Hoveyda-Grubbs type for initiating the ROMP and at least one retarder selected from the group consisting of heterocyclic a means having a ring with at least one N-atom and four or less other atoms constituting the ring bearing the at least one N-atom. The invention further relates to a process for the preparation of a composition which is polymerizable by ROMP, a dental material obtainable by polymerizing a composition according to the invention and the use of a substance selected from the group consisting of heterocyclic amines having a ring with at least one N-atom and five or less atoms constituting the ring bearing the at least one N-atom or of a mixture of two or more of such substances as a retarder in ROMP.

Compositions curable by ring opening metathesis polymerization at low temperatures and their application in the dental field

The invention describes solid materials, especially for dental purposes like, e.g., composite milling blocks (CMBs), which can be obtained by ring-opening metathesis polymerization (ROMP). Also described is a method for obtaining such milling blocks, their use and applications of the compositions.

Solid materials obtainable by ring-opening metathesis polymerization

The present invention is directed to dental compositions that can be used as adhesives for bonding a dental material to a dental structure surface and/or as a dental restorative material. The dental composition is preferably applied to a dental structure surface under conditions effective to etch the dental structure surface.
