低温下通过开环易位聚合反应可固化的组合物及其在牙科领域的应用
摘要：
本发明涉及可通过开环易位聚合反应(ROMP)聚合的组合物，所述组合物包含至少一种可通过ROMP聚合的单体、至少一种用于引发所述ROMP的所述Hoveyda-Grubbs型引发剂，以及至少一种选自由杂环胺组成的组的缓聚剂，所述杂环胺具有由至少一个氮原子和四个或更少原子构成的环，所述环具有所述至少一个氮原子。本发明还涉及用于制备可通过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，以及选自由杂环胺组成的组的物质或者两种或更多种此类物质的混合物用作ROMP中的缓聚剂的用途，所述杂环胺具有由至少一个氮原子和五个或更少原子构成的环，所述环具有所述至少一个氮原子。
摘要（英）：

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 atomsconstituting 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 bypolymerizing 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 atomsconstituting 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.
