Polymers from ring-opening metathesis polymerization (ROMP) of norbornene derivatives have backbone structures which are distinct from those prepared from radical or anionic polymerizations. The unique backbone structure, along with the high functional group tolerance of various ROMP initiators, make ROMP polymers interesting targets for molecular engineering and self-assembly investigations. We have recently developed various functional monomers, such as photoreactive monomers, bifunctional monomers having heterocyclic cores, and semifluorinated monomers having up to 34 fluorine atoms per monomer, as building blocks for molecular engineering of polynorbornenes from ROMP. Herein, the design principles of the monomers, along with their synthesis and polymerization are presented. Self-assembly of block copolymers from these monomers are discussed, including star-shaped polynorbornenes prepared from core-first strategies involving multifunctional norbornenes. |
