摘要：
The present invention relates to novel bicycloaliphatic 2-methylene-1,3-dioxepanes, which are suitable as starting materials for the preparation of polymers and copolymers, preferably of composite and dental materials. The 2-methylene-1,3-dioxepanes according to the invention, which can undergo radical polymerisation with ring opening with only very little volume shrinkage, can be prepared in a simple manner, are easy to purify and to modify chemically, and are characterised by lack of odour and advantageous physical properties.
