    • 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.
    • 本发明涉及通过开环易位聚合(ROMP)可聚合的组合物,其包含至少一种可通过ROMP聚合的单体,用于引发ROMP的至少一种Hoveyda-Grubbs型引发剂和至少一种选自 由具有至少一个N原子和四个或更少的构成具有至少一个N原子的环的其它原子的环的杂环化合物组成的组。 本发明还涉及一种制备可通过ROMP聚合的组合物的方法,可通过聚合根据本发明的组合物获得的牙科材料和使用选自以下的物质:具有环的杂环胺 构成带有至少一个N-原子的环的至少一个N原子和五个或更少的原子,或者ROMP中的缓凝剂等两种或更多种物质的混合物。
