General description
Ring opening metathesis polymerization (ROMP) monomers are attractive building block for advanced polymeric materials in the biomedical field. (5E)-2,2-Diethyl-1,3-dioxa-2-silacyclohept-5-ene, or the silyl ether based ROMP monomer EtSi, is a bifunctional cyclic olefin that can be used to synthesize a variety of macromolecules and polymers with diverse compositions and complex structures. EtSi can copolymerize with a variety of norbornene derivatives including small molecules and macromolecules, enabling the formation of backbone-degradable copolymers that can be used in a variety of biomedical applications. The ROMP polymerization method is superior as it permits the tailorability of the resulting polymer material.
Application
Synthesis of advanced polymeric materials for biomedical applications including:
- drug delivery
- molecular imaging
- self assembly
- hydrogels
- medical device coatings
- stimuli responsive material
Features and Benefits

Ring-opening metathesis polymerization of norbornene-based (macro)monomers is a powerful approach for the synthesis of macromolecules with diverse compositions and complex architectures. Nevertheless, a fundamental limitation of polymers prepared by this strategy is their lack of facile degradability, limiting their utility
