General description

Ring opening metathesis polymerization (ROMP) monomers are attractive building block for advanced polymeric materials in the biomedical field. 2,2-Diphenyl-1,3-dioxa-2-silacyclooct-5-ene, or the silyl ether based ROMP monomer PhSi, is a bifunctional cyclic olefin that can be used to synthesize a variety of macromolecules and polymers with diverse compositions and complex structures. PhSi 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

  • Copolymerize efficiency with a wide variety of norbornene-based (macro)monomers
  • Controlled ROMP polymerization
  • Silyl ether substitute can be tuned to control degradation

Bottlebrush polymers are synthesized using a tandem ring-opening polymerization (ROP) and ring-opening metathesis polymerization (ROMP) strategy. For the first time, ROP and ROMP are conducted sequentially in the same pot to yield well-defined bottlebrush polymers with molecular weights in excess

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

Materials capable of degradation upon exposure to light hold promise in a diverse range of applications including biomedical devices and smart coatings. Despite the rapid access to macromolecules with diverse compositions and architectures enabled by ring-opening metathesis polymerization (ROMP), a
